I had some strange symptoms last night before going to sleep during my practice sessions. I could see a lot of fractals if I closed my eyes, very similar to how you can on psychedelics. I also was in pitch darkness, but sometimes if I closed my eyes I could see very bright light, almost like daylight. It was very bizarre. All of these alongside the normal physical symptoms I get while trying to RV, like circular flashes with my eyes closed and green light.

That's normal stuff which happens to everyone when they go to sleep. You just don't remember it. 
It's connected to RV in that it has to do with alternate states of consciousness. 
John Vivanco in his book The Time Before the Secret Words calls it remote viewing when this state is used to generate ideas. He mentions scientists like Edison who used to fall asleep in a chair, holding marbles above a pie tin. He would get into the hypnagogic state and would let go of the marbles, falling into the pie tin and waking him up.
