It happens on random occasions, say multiple times a month or years in between. I figured its weird, but it doesn't really cause problems, just annoying. Would be nice to know what it actually is. Usually happens when laying in bed.
Say you slip on ice, you feel the sensation as it occurs, which is normal. I'm laying down and my body/mind feels the sensation of slipping on ice (as if it just occured, despite just laying there) causing automatic reflexes of legs and arms moving to try and stop the fall with increased heart rate. Lasts only like a second of the sensation/muscle jerk. There are other sensations too, not just like slipping on ice. Once had a root canal (too little sedative so could feel the drilling of the root), up to a week later could feel the sensation as if it was actively occurring despite doing random stuff.
Another example is hearing, same as above, say hearing a car honk, you have the sensation of hearing the noise, the distance of where it occurred, the recognition that there was a car honk. Again, some random time, usually in bed, I have that sensation as if completely it actually occurred, despite knowing it didn't.
Usually the hearing occurs a lot less than the feeling one. There doesn't seem to be any connection with recent activities to correlate with the sensation felt. I've had this for probably like 10+ years now (am 25). Doesn't seem to be a reason why it occurs or why at certain times, again occurs rarely, but enough to notice that there's something wrong. Have asked a few people and they say they have never experienced the above.
It would be nice if I knew what it was and if there was some way to stop it. Thank you for any help provided. Sorry for the long post.
