    I can rumble my eardrums. Mostly useless unless i wanna block out some annoying sound but i can only do it for like a minute at a time.

      I think I have the same thing. Is yours also kinda connected to blinking? I can do it without blinking, but closing my eyes at the same moment as rumbling the eardrums feels easier and more natural than rumbling with eyes open.

        I can do it without closing my eyes but when i was younger, I remember closing my eyes or scrunching my face made it easier to do. If you can wiggle your ears without lifting your eyebrows, it kind of feels like its the same muscle group that causes the rumbles. The rumbling sounds like white noise inside my head. Its caused by constricting Tensor Tympani muscle in the ear voluntarily. From Wikipedia:

        Some individuals can voluntarily produce this rumbling sound by contracting the muscle. According to the National Institute of Health, “voluntary control of the tensor tympani muscle is an extremely rare event”,[5] where “rare” seems to refer more to the scarcity of test subjects and/or studies more than the percentage of the general population who have voluntary control. The rumbling sound can also be heard when the neck or jaw muscles are highly tensed as when yawning deeply. This phenomenon has been known since (at least) 1884.[6]

          TIL; I always thought it was temporarily spiking your blood pressure that made that rumble. Now I’m no longer scared to do it

        I do this thing where I pop my ears (like when pressure changes from altitude) and then it’s like I’m hearing my breathing inside of my sinuses or something. When I breathe this way, it effectively blocks conversations I don’t want to overhear. Do other people do this, or am I odd?

          I can do this. If I’m in a really quiet area, I like to take in a deeper breath and then exhale as slowly as possible while doing it, which then allows me to hear my heartbeat. Super nifty.

          I can also use my soft pallet to block airflow from my throat to my nose. Can you do that too?

            I can’t block my nose in that way. I tried when your comment came in, but I can’t conceive of how to do it.

            With the ear popping thing, I just hear the rushing of my breath. I can see how you might be able to hear your heart. I might be making this up in my head, but I feel like maybe I could hear it when I was younger.

              The trick is that while you hold your ears ‘open’, you have your lungs try to not breath out but you don’t close your mouth. This lets the heart beating against your lungs be what pushes air in and out and then you hear the sounds of the air pulses as it moves past your eustachian tubes in your throat. Making sure your lungs are as full as possible is required so the lungs push against the heart.

          I can do this! I forget the name for it but I can rumble my ears, and then I can also ‘pop’ them if I go a little further. I’m so grateful for it if I ever go through a pressure change, I can’t imagine how people cope without being able to do it.

            Wait a minute. If I hold my jaw right, I do get a very short rumbling apart from my breath. Is that what you guys mean?

              Sounds about right. I would connect this action to my jaw, not anything with my eyes like some others have said. When you say short, do you mean the sound doesn’t last very long? I can keep it going more or less as long as I want.

                As long as I tense my jaw, I guess, but it’s kinda awkward for me. I kinda have to pop my jaw down and hold it. I feel I’m making a silly face when I do it, so I’m not holding it long.

                  I guess there’s multiple ways to hit it. I feel it in my jaw but it’s the same process as wiggling my ears (though I don’t have to do that at the same time if I don’t want to).

          Came here looking for the tensor tympani rumble cause I know it well; not sure what your thing is! If I notice sounds going quiet on a flight I’ll pinch the nostrils shut and make an exhalation effort till I hear a pop in each ear, then sounds are normal. Almost like the reverse of yours.

        Same. I hold my eyes shut and I can activate it. I like to think of it as my automatic ear-cleaning mode.

        I can also ear rumble, it is not tied to my blinking at all, but if I vibrate my eyes while my ears are rumbling they both move at the same ~60hz frequency.

    This is my time to shine, my body is full of useless, I can:

    • gleek intentionally (saving people a search: it’s causing the salivary glands under your tongue to shoot saliva, people often do it unintentionally when yawning)
    • open my jaw wide enough that it goes out of socket, and twofer I can then move it side to side and produce a loud popping noise
    • bend my thumb down to my wrist
    • cause my heart rate to spike for short periods even when at rest
    • make a three leaf clover with my tongue
    • click my tongue extremely loudly

      I remember when I was a kid we were all trying to gleek and some of us could do it easily. I never could, so anytime as an adult I accidentally do it, I can’t help but laugh.

        It has “force”, but it’s not very impressive, I can shoot saliva in approximately a 1ft / 30cm arch.

      I can also gleek but it’s nowhere near what my grade 11 English teacher could do. I don’t know how it came up in class, but, in front of the class, she turned sideways and made the biggest arc I’d ever seen: maybe 6 feet long

    You know that feeling you get when you listen to really awesome music and your hair stands on end and your skin has like an electric tingle all the way up and down? I can do that feeling at will. It’s called ‘voluntary frisson’, normally an autonomic response. Makes music a real.trip.

    I can voluntarily open my eustachian tubes and hold them open, without needing to yawn or swallow. Makes it much easier to clear the pressure in my ears when changing elevation (like when flying in a plane).

    I can twitch my eyeballs left and right really fast, and not just a little bit - but most of the way.

    Completely grosses people out when I do it.

    Edit: I can even do circles, but not as fast as left and right.

    Apparently there’s a thing called lucid dreaming that many people try very hard to achieve.

    Most of my dreams are “lucid”.

    I can also, using only my facial muscles, pull my eyelids back extra far so it looks like my eyeballs are popping out.

      I have a hypothesis that there is no such thing as lucid dreaming (before you get the wrong idea, I’ve done it before. My meaning is that it’s misunderstood, not that people are lying about having done it).

      That feeling that you’re in control? You’re just dreaming that you’re in control. You’re just dreaming that you have the experience of choice-movement-feedback.

      How is the feeling of being in control any more real than other sensations you experience in a dream?

      When you experience the sensation of enlightenment in a dream, do you say you were really enlightened, or were you just dreaming that you were enlightened?

      When you experience the sensation of blue in a dream, do you say there was actually blue, or were you just dreaming there was blue?

      Your brain telling you you’re in control is just as suspect as your brain telling you there’s blue. They are both creations of your brain for the purpose of the dream.

      Whatever action you’re taking in an attempt to demonstrate control is just as easily explained as something your brain created as dream decoration.

      Remember, this is just a hypothesis.

        The question is, is there a practical difference between lucid dreaming and dreaming about being lucid? I like to think it’s the memory afterwards that counts.

    Lots of things that ultimately come down to hyper-mobility (thanks Ehlers-Danlos!), including:

    • Lick my elbow
    • Pull my shoulder visibly out of socket (not painful at all, and happens if I carry something heavy if I’m not careful)
    • Pop my hip out of socket while standing (sometimes painful, always somewhat unpleasant, so I’ve had to learn how to not do it)
    • Hold my hands behind my back and pull them to my front
    • Rotate my arm >360°
    • Bend my thumb to my forearm
