Astral Porjection Options

is it normal for my body to bother me (especially my legs) when astral projecting?
they feel like stiff

how bout staying on the ground? I have a hard time staying on the ground. Is it a common problem? (While we're posting questions, hey what the heck?)

I think it might have to do with the psychology of the situation. At least when I think of astral projection I think of "flying" out of my body. I'd bet many other people hold similar beliefs. Thus I'd also bet most people tend to believe they are flying while projecting. In fact I can't recall a time when I was actually grounded while projecting. I guess the method I usually use might be the cause as well as I visualize myself lifting from my body. Other techniques might have you stand up from yoruself rather than fly out of yourself.
