I have been learning to astral travel, putting my body to sleep etc.

I lay down, cleared my head, my body was relaxed. After about 15 mins, my body was vibrating. I tried to lift my arms up out of m body starting with my hands. I don't know if somebody could tell me but it felt as though a hand was peeling away (best way I can describe)
I didn't want to go past this stage (for now) as I want to master the first part.

I opened my eyes and my body was tingling as if the blood circulation had been cut off. I managed to move my legs, but one of my arms would not move. It also hurt when I lifted myself from the lying down position.

It took about 10 mins for me to be able to move my arm properly and they still hurt as I am writing this. Is this feeling normal?

It is starting to get better as my legs and shoulders are completely fine.

It is like I have pulled a muscle i both my arms, is this normal or is this because I was trying to rise my arms up first?

If anybody else has this, how long before it usually goes?
Or is there a technique to slowly awaken your body?

Thankyou
