okay so ive been trying to astral project for about a month now and the only time ive ever hit the vibrational stage is when i sense there is something wrong in my dreams. (Nightmare) i only feel these vibrations when i have nightmares. is it my fears? i have already gotten over them.i practice not only in reality but also in my Lucid dreams. is there something im not understanding or something else im supposed to learn how to do before i astral project? Any advice anyone?
