I have a legitimate disorder if I get woken up suddenly during a certain part of my REM cycle. I go into a kind of fugue state for around 30 sec-1 min until I truly wake up. During that short time I am PISSED OFF at everyone and everything. I have done some really weird things during these fugue states, but luckily I only wake up "incorrectly" once or twice a year.

I have obviously yelled at people, but also have some ridiculous stories like the time I ran into the kitchen to protect my Pillsbury Biscuit dough from being eaten by my friends whose laughing woke me up. But, as soon as I calm down and truly wake up, I understand what I just did and cry because I said/did things I normally never would.

I recognize that it is a weird thing my brain does and try my best not to react that way. I am getting a little better, but it still happens from time to time. Heartburn seems to set it off really bad. Also, sleep deprivation makes it worse, so I try to nap more.
