Someone told me that if you keep your gaze fixed and imagine a completely black circle right above someone's head, what you are actually doing is telepathy... so far I haven't researched more about it but I have noticed that some strange things happen when I do that, I see spirals and the vision looks different, could someone confirm what your experience is when doing the same?
Edit: As someone said in the comments, have you ever seen an image in black and white with a red dot in the center what if you keep your stare fixed for a certain time in it and close and open your eyes rapidly you see the image of JesusChrist? Maybe it is realated to the phenomenon in some way.
If someone try it and notice some result please let me know.
Oh, I remember I did this in kindegarden. I didn't have anything better to do during "activities" so I just stared down the caretaker(? I'm not native). Not long after halos and outlines apeared around her. My child self tought she was some angel. Anyways good drugless trip.
