Sometimes I feel like I have to keep my soul in my body?

I dont really know how to explain it. I dont feel like its astral projection (however you spell it) all the women in my family have to a certain degree paranormal things about them. I for example have a sort of premonition. It usually is things that will happen in a dream and weeks later i find myself in the same situation and i know I have to change something about it. I often feel like I am being watched and have had ghost experiences. but anyway on to my question. Ever since I got my panic attacks about in Dec 2008. I feel there are times when I am just sitting or doing whatever and i feel like i start to see things outside of myself differently and i have to pull myself back into myself. I dont know if that makes any sense at all. I dont ever leave my body but I heard that when people are dying sometimes they hold on longer and it actually can make people live longer. and when people are ready to go they go. I would say its similar to that only Im not dying. Explain?
