Jerking in my thoughts?

Depends on how often this occurs. This sort of thing happens to everyone and is pretty common. Your body is getting ready to sleep and an outside sense or scary thought snaps you out of it. This happens to me everytime I get a boring lecture and try to sleep with my head propped on my arm.

If this sort of thing is happening while you are trying to get legitimate rest and is keeping you up every night then It could be a sleeping disorder or anxiety. Likely developed by bad habits in life or stressful events. Not a huge deal though. But if its just sometimes when you're tired and out somewhere then we all know how you feel lol.

It happened to me in my sleep many times.. I wake quickly and my heart is beating fast. But then I go sleep again. Youmust do the same..

i do that all the time!!
when im half asleep, i kinda dream of im going down the stairs and i just trip and falls, then i jerk and wake up all of the sudden. its not as creepy for me, cuz it happened like many times.
totally normal, I think i read an article explaining it, its like when you fall asleep, you breathe slower, and your heart beats slower too, so ur brain thinks ur dying, so it rejects a stream of electricity?? to wake you up and prevent you from dying :/

All answers above are nonsense. What you experience, from this question, could be described as anxiety in your waking life. Also, when you lucid dream, you tend to 'snap out' of it, giving you the jerking effect.

I never fall in my thoughts but I fall in my dreams all the time and jerk awake in the same position I am falling in!

Falling in your sleep,well that's not that weird,i've also felt that,i guess everybody's felt that,some people say that it's related to spiritual causes,could be your astral body trying to get back to your physical body

Yeah, i heard that when that happens in your sleep, your hearts about to stop.But I dunno, :/

I do the same thing but its mostly from habits ive developed over a life time.

ManaX, you're just gonna worry the kid. It's normal dude. People do that to snap out of a thought that just went a little further than it should have...

Normal. Rarely for me but it happens. Happens more or less for everyone. Normal
