What is wrong with me in those times?

Sometimes I just break down.Immobilize is a better word for it...It happens when I don't remember something,my body can't seem to move nowhere,if I was to lift my hand up or grab something,I couldn't move it.A thought keeps blocking me.Then I remember a thing I had to do already before and I am "free" again.This phenomenon happens seldom to me.But it's kinda special to me,like a D�j� vu.Isn't this thing related to the mind and body relation?I didn't want to move because I somehow knew I did something wrong???
