^can you elaborate on the location of your mystical inner-ear-dog-whistle? sounds VERY interesting and i'd really like to know more!
You know when you yawn, that pressure in the middle part of your head,, as well as on the outside of your jaws, where your wisdom teeth are, its kind of like flexing that inner part of your head...
try moving your jaw forward, literally bottom teeth past front and as far as you can, you'll feel it kind of and probably hear it...
I just do it sitting still not really moving...
Its located around where I believe the pineal gland itself is, as well as the pituitary gland, so I dunno if it has any correlation to the actions based off the part of your brain which produces DMT and the secretions of the brain from those points..
I find on DXM I can do it very strongly and can hold it for a long time, Ketamine im just too fuckard... on Shrooms... well I won't go there, a tiny bit made my entire head just go fuckzard...
Then I moved here to Afghanistan where psychedelics don't exist, so hopefully once mushrooms start sprouting I'll find some liberty caps, sheep and cattle graze the lands everywhere, and the area I'm at is at a good place for them to grow nicely...
