There have a been few times where after I've gone to bed where I've abruptly woken up by my head/body slamming down on the bed - almost as if I've been sleep walking and gone back to bed and thrown myself down on the bed. Anyone else here do the same thing?

I also wake up constantly by my body jolting/twitching in the middle of the night and I'm a very violent sleeper (as I've been told) I kick and punch all throughout the night without being aware I'm doing it - also wake up constantly to my pillows and blankets on the floor or across the room

And just last night, I had just fallen asleep and I woke up literally what felt 2 second later feeling like I had been electrocuted.. My body felt numb/tingling like I had been shocked and I could tell my heart had stopped as it felt strange and was racing extemely fast and I was out of breathe. I was too scared to go back to sleep after that incase it happened again. I didn't dream I was being electrocuted, it just randomly happened the second I fell asleep

Anyone else relate to this, or can explain it?
