My reoccurring hallucination is mostly auditory, i think it's mainly my fan's noise being distorted though. Large vibrations throughout my body, kinda of like energy waves crashing over my body. Once I am in SP I start seeing shifting beams of multicolored light. Then I am in the "void" as I call it. Where you are conscious just not in a particular dream, just surrounded by darkness, yet you can fully move with no restrictions. Its the same thing every time!
