Oh sure, it's hilarious to watch a sleepwalking loved one wrestle an invisible dinosaur, until you try to wake them up and they FREAKING KILL YOU.

ABC News recently warned of the potentially deadly consequences of messing with a sleepwalker, based on a recent case written up in the American Journal of Psychiatry that suggested sleepwalking was a viable defense for murder.

Here comes the science: Sleepwalkers lack the mechanism that paralyzes them in their sleep and keeps them from acting out their dreams. Because they're capable of walking around with their eyes wide open, it may seem like they're cognizant; however, they're often incapable of recognizing faces, which is why one night your husband might assume you're a gigantic anaconda in his bed and try to lop your head off. (Or, on a lighter note, based on many of the stories we'll share after the jump, he might just rummage in your closet or take a leak on your computer.)

"They are very good at navigating space," sleeping-disorder expert Rosalind Cartwright told ABC. "They can go up and down stairs and drive a car. They can navigate in the world, but the face recognition is off."

The important thing to remember is this: Don't try to wake a somnambulist, especially one who's been stressed out, since that's usually when things tend to get all homicidal.

Fortunately, violent sleepwalkers are very rare -- most are of the harmless, hilarious, "making weird stuff in the kitchen" variety, which is actually pretty common. Check out some of our wackiest encounters with sleepwalkers, then leave your own in the comments.

"I have that disorder where I try to have sex with people in the middle of the night while I'm asleep! I used to think I was just getting creepily night-touched by male friends over and over again, but then realized I was 'making the first move' and only waking up when they were reciprocating. Once a friend in college told me that she woke up and saw me with my shirt up, rubbing my nipples in the middle of the night while I was completely REMing." -- Lillie

"I have woken up naked on the living room couch in two separate apartments, both times within a month of moving in with strangers." -- Tim

"My friend David Kent has peed on his computer in his sleep. Multiple times."
-- Thea

"One time my mom caught my stepdad eating raw rice straight from the bag in the kitchen when he was asleep. And another time he wouldn't stop screaming about 'space monkeys.' It's always fun to go home for the holidays." -- Em

"The last time my girlfriend caught me sleepwalking, she said I awoke her by grabbing at her breasts. She realized I was out of it and yelled, but I didn't answer. I just got up and began digging in my closet. I apparently didn't find what I was looking for, walked into the kitchen, turned on the water full blast, let it run for awhile, turned it off, and walked back in the room to sleep the wrong way in bed, with my feet by her head." -- Ryan

"My doofus ex-boyfriend once woke me up in the middle of the night for the kind of tender, slow sex rarely seen outside of Nicholas Sparks films. I was like, 'Wow, I never knew he had that in him.' Ha ha, turns out he was asleep the whole time." -- Julie

"My sister sleepwalks anytime she sleeps somewhere new. When she came to visit me for the first time, she woke up in the middle of the night and started slamming the doors around the apartment, then walked into my roommate's room -- still dead asleep, mind you -- and started talking nonsense and yelling at her. All you can do is guide her back to bed and hope it doesn't happen again." -- Eilene

"After my first night of college, a lovely girl named Ellen from down the hall (we had met the day before, in the fabulous community bathroom) knocked on my door asking if I was OK. I apparently had stormed into her room the night before and ripped open the empty closet as if I were searching for something. Whenever she would ask what I was doing, if I was all right, etc., I would shush her and tell her to go back to sleep. After not finding whatever the hell I was looking for in the closet, I started sizing up the empty bed. I'm not sure how long this went on, but definitely long enough to scare the hell out of Ellen." -- Andrea

"Once on vacation in Mexico I had a dream that my boyfriend was cheating on me -- only, just like described above, my body isn't paralyzed when I sleep, so I actually act out my dreams. In this case, I woke him up, much to his surprise, with an amazingly well-placed punch in the face." -- Wendy
