I've been meaning to lookin into this for a long time now. Ive been experiencing what I could only describe as a crystal cracking into shards brain piercing electric shock which was first experienced when on my first aya journey. Now the crazy part is that I get this brain shard almost every night now before I fall asleep and it's accompanied by visualizations. It feels good in a weird way and I feel like its actually oppening up parts of my brain that have been dormant. Hmmmm maybe it's my pineal gland breaking down those stubborn flrouide crystals lol.

When I have smoked DMT, for some reason on dark fractal trips I would get an electricalesque, static twitching by my eyes and forehead. Did not seem right but I rode it out the couple of times it happened and it would fade.

DMT has definitely made my mind more aware of certain activity that I am either more aware, DMT has activated or both. Sometimes when I sleep I feel a pulse in my head by my left temple that causes a strange involuntary sound to emerge, but nothing like the twitching when actually taking DMT. Just thinking about Spiceland laying down before I go to sleep is enough for all sorts of energy to be activated... its powerful stuff even if I do not smoke it for months. I wish I had known more about spiritual phenomenon before I delved so far into that world, lol. Its fantastic and an immense journey of learning and change ahead.
