The first time i took (hawaiian)shrooms more than a decade ago, i was standing one hour infront of the mirror and was watching in awe how my face morphed/melted into various south-american indigeous shaman archetypes inclusive their hats and decorations.
There was no egoloss, just an pure visual and extreme euphoric trip. The images in the mirror had an extreme otherwordly quality. It wasn't just distortions and frame overlays, i really saw my face morphing into a hundred other destinctive faces with completly different facial proportions than mine, and they would stay like this for an amount of time (a minute),smile at me, look deep into my eyes before changing again.
Some of them looked like the Shipibos, they had their hats with the usual patterns.
The only strange thing is, that at this time i did not know anything about this tribe(or others), nor did i had knowledge of the shipibo pattern art and their clothes.
When i later watched Jan Kounens "Blueberry" (Renegade in the US), it absolutly floored me that the shaman looked EXACTLY like the image in the mirror i saw years earlier.
Another thing: i would absolutly suggest everybody to be careful when gazing at youself in the mirror over a longer time. Don't do this if you feel unstable or a little depressed, or if you are in general not so experienced with psychedelics. It can and will bring something up you might not expect nor want. Seeing the ugly, hidden, darker side of oneself can be the result of that exercise. And what has been seen, cannot be unseen.
I have psychonaut buddys who refuse to do this as it freaks them out.
