Had this dream a few weeks ago, but I wrote down the details I could remember. It was a lucid dream, and in my dream I was lying down on a bed or a table. Knowing I was dreaming, I concentrated both my eyes on the point between my eyebrows. Instantly I felt a rush of energy growing stronger and magnetizing towards my brow. As I looked in, it was like looking down a cylinder. In the center was a purple spinning vortex, and on the sides there were what looked like glyphs displayed. The energy quickly became very intense and I ceased concentration as I became worried I would harm myself. I woke up with my brow area stimulated. Any interpretations of what could have been going on?
