Transmittion of visualisation works too.
I was once on shrooms and with a friend (he was sober), we played a little game, i was to visualize something, while he stared at me and tried to get my vision.
I thought about a rainbow colored snake moving in spiral form, which was promptly transmitted as he jumped back with a shocked look in his face.
He told me he saw exactly was i was visualising, a colorful snake jumping in his face, coming from the area of my third eye, moving in a spiral.
We tried again, but without success. The difference to the first one seems clear, we did it without an expectet result the first time and it worked flawless, afterwards we had some expectations.
Also, the whole thing was strange, i ate the shrooms but stayed sober and clear, while my buddy was kind of tripping, he saw my aura and shit...
