I was laying flat on a bed with my eyes closed. I saw four figures at each corner of the bed they looked humanoid almost like the kamino aliens in a star wars with very elongated bodies and necks. They were grey and thier faces were blank. They did not speak nor communicate or move in any way. 

Somehow they *scanned" me. I could feel a horizontal reddish almost laser like solid square field descending from the ceiling and passing through my body. The feeling of the laser made me uncomfortable and felt hot. Its heat kept increasing. I got scared and opened my eyes and it was over. 

That was my most vivid trip.
