I woke up not knowing who I was?

This has been on my mind all day today. Last night I woke up in the middle of the night to turn off my music (I usually listen to music to fall asleep, but it was distracting me that night). As I did so, I felt this weird sensation and didn't know who I was. I felt like I was dreaming and like my brain was constantly asking me "Are you really you"? I looked down at my hands which scared me even more, because it felt like my hands weren't apart of me. At one point, I started to panic, and I tried to calm down by repeating what my name was several times and breathing. I commonly feel like I'm in a dreamlike state during the day, but it's never hit me this hard before. After that whole fiasco I feel very out of it, very frustrated, and sad; like I'm on the verge of losing it basically. I am very curious as to what happened and why?

This is very normal.. Happened to me a lot when I was younger. I think this is caused by a sudden wake up from the REM stage of sleep; it takes a while before the mind comes back to the body.

Can't speak to what's happening to you in the daytime, daydreaming is pretty common but you suggest this is something else.  It's often just a loss of focus as the brain does its thing.  At night, though, it happens sometimes, we wake up and we were sleeping deeply and so we're not quite awake yet and not asleep anymore either, and so for a minute you're not quite sure where you are or what's going on.  Then you wake up completely and it goes away.  Anxious people can make lots of things part of their anxiety, but you probably experienced this when you were a kid a lot but just thought it was completely normal.  Like when you fell asleep in the car and woke up when your parents were putting you in bed, you probably had that feeling but didn't worry about it, you just went back to sleep.
