Dreamt I was on some weird punk concert, with a band in their late fourties or fifties, and we were inside a school building with teachers and students, but the band was playing damn raw, aggressive and somewhat dark punk music, to which we were jumping around and poking each other… then suddenly I found myself in a different place, everything was dark and warm around me and infront of me was floating a huge brain in its sleeping stage. The brain was just mega-big and floating in space. There were spotlights highlighting it, whilst it kept turning around its own axis. First it looked all even and smooth with no gyri, and a literal ‘veil of sleep’ was covering it. But then the veil was lifted and the surface changed so that suddenly one could see the pulsating arteries, the veins and gyri. The light was like in a museum’s display cabinet, but the brain itself appeared as tall as a whale and the space around it reminded me of the deep ocean. I was entirely fascinated watching this thing from all sides but then I was woken from sleep and had to get up.

NB: The brain condition known as “smooth brain” (lissencephaly) exists for real:

Interesting that the smooth brain was associated with the music you were listening to, which most likely had a theme or message of its own, and seemed to be negative?
then the brain “healed” as you left the dark music, and a veil was lifted from the mind.
what we feed the mind either darkens it or enlightens it.
truth heals. God heals.
