this morning I started to see these waves about 15 mins into meditation. every time I'd breath out, I would see a wave coming from the top towards me. it wasn't anything colorful or visual but more of a subtle energy amongst the darkness. then at some point it started to move from top to left. *breath out* wave coming from top left towards me.. *breath out* more left... then at some point it started to come from my left and disappeared.
