Hi,
I've been attempting astral projection for a while now, but there are times that after I decide to go to sleep after not being able to astral project that I fall into a certain state that I hear a white noise that's really intense and hurts mentally and wakes me up every couple minutes. At first I would just let it happen cause I was curious to know what it was but really it just seems to be it, just that ear ringing sound that's in my head that comes with a feeling similar to sinking in your body. Once I'm trying to sleep, I don't want that feeling so I try and snap out of it as you do when you meditate but it doesn't go away. It keeps me awake for a while and then I go back to sleep, and then again with it until I get out of bed and do something for a couple minutes and finally I'm able to sleep again. Does anyone know what it is? Thanks for taking the time to read and help in advance.
