I dont know if this is related or a medical issue, Ok i tried going to sleep a few minutes ago i wasnt really concentrating on anything and then my body started to feel weird not a tingling sensations but something along the lines of that and i started feeling that my eyes were moving really fast or vibrating or something, they have done that before i haven't been paying to much attention towards it, but anyway i was wondering if this is a sensation i should embrace to attain lucidity or if this was something just my body does normally?
