According to my mom I used to curse (really loud) in my sleep, lol. I could hardly believe her.

One time I woke up with my head underneath the pillow. Mostly I move around a lot when I sleep.

i have not done anything wierd in my sleep but when i was sleeping over at my cousin she sat up and started singing the song called thriller by micheal jackson in her sleep

I'm pretty old now (well, middle-aged) and sleep like a log these days - I can wake up in the exact position I fell asleep in as I go out like a light. When I was a kid though I went through a period of sleep-walking (had a scary infants school teacher and my mother thinks that was why I started sleep walking). One day I walked to the neighbor's house and knocked on their door, at about 4am in the wintry snow! My father came out to retrieve me.
In my teens I had a habit of making clicking noises with my tongue apparently. Not sure what that was about.
I think I might snore slightly these days.

once my dad started telling my mum our home phone number while he was asleep

Wow, those last two... were you dreaming or did you just turn over and had your arms spread out??

My mother still denies that she snores nightly-no, not just when you have a cold or allergy problems, you do it nightly. It's how I know you've fallen asleep in your chair watching tv on days when I'm visiting.

My sister sometimes talks in her sleep a bit.

Myself, I used to do laps in/around the bed when I was a little kid, but I started staying put more before I hit puberty. I've never been a sleepwalker, however, there was one odd incident when I was about 11 and had a dream about getting in a fight with a girl in my class I didn't like (I didn't do that in real life), and I woke up choking my pillow.
I went through a drooling stage in my teens.
Now I mostly just hug a pillow, although every once in a while I still get an occasional Hypnic Jerk (even without dreaming I've tripped/am falling, sometimes it'll happen right as I'm nodding off), which is something that's happened to me on and off my whole life.

Of course, that's when I actually sleep. I can be a bit of an insomniac at times--the type that puts off falling asleep as long as possible, or just can't wind down enough (no matter the various ways I've tried over the years, barring sleeping pills, which I don't go for) to fall asleep. Once I do conk out though, I'm dead to the world. The things I've slept through over the years include:

The aftershocks of a very small earthquake.
A fire alarm going off in my college dorm (justified in that the thing was faulty and something set it off at least once a week, including things like the pipes freezing).
A tornado nearly forming above my neighborhood.
At age 7, my neighbor and best friend's townhouse apartment (that actually shared a wall with ours) catching fire, the fire trucks parking on the common lawn with sirens blaring while they fought the fire, the firemen tramping through our apartment in full gear to talk to my friend's mom because they were spending the rest of the night with us (our moms were also friends), and then my mother and friend's mother tucking her into the same bed as me (I'd inherited an older hand me down, full or queen-size bed from an aunt, so there was room)---but woke up instantly and practically shot halfway across the room when she rolled over in her sleep and lightly brushed against my hand or something...

I usually dream that I'm jumping or flying, and I'm scared of heights. I once laughed so hard in a dream that I thought my brother heard me, but he heard nothing.

when I jump off something high of fall down the stairs in my dream I get a Hypnic jerk. It also very rarely happens when I'm about to fall a sleep.

Once, my dad had an Hypnic jerk when he was a sleep which caused him to fall out the bed, he woke up in the morning, on the floor in-between the bed and the set of draws next to his side of the bed.

LOL! That's awesome, Nymphetamine!

Aside from sleeptrips to the toilet proper, I talk in my sleep, which worries me, as I was told this by my father, who knows very well that he left an imprint on my being and it would explain my adoration for men as old as my father and older, and his grin was not unlike the famed British Shorthair and the persona of the Cheshire cat...Well, I hope I wasn't dreaming of sex and was audible to my father who is a light sleeper compared to me and mom and I forgot the dream. The other thing was the January 15, 2015 incident. I slept naked half the night and I have a very fuzzy recollection of when I stripped down in my sleep. At least my parents got up AFTER I got redressed.

That happens to me, too. Usually, though, it's only when I fall asleep on my back, since I end up dreaming that I trip on one of my little sister's blocks or one of their toy baby bottles. Good thing is that I wake up before I hit the ground.
