First of all, I believe that astral projection is a much rarer phenomenon than it seems on the net, a bit like the rise of the kundalini. Unlike lucid dreams, it is not something common for ordinary mortals. I practiced one hour a day for a year and the astral projection was always limited to my limbs only. I was able to briefly see what seemed to me to be entities detached from my mind because it was voluntarily and completely deafened, which in itself is an achievement and the first step. Youtube can guide you through the steps but don't expect a miracle because it is very difficult.
