Hello, I've recently experienced a subtle state of awareness during sleep. It was neither dream nor deep sleep. There was not connection with mind (thoughts), body, senses. The sense of ego/I/individuality was very subtle or diluted in the whole. Can it be compared to a state of samadhi attained through yogic practices? Later, the same night I've also experienced an "energy body" trying to leave the physical body, like it was trying to sit in the bed.
