10 years ago, I'd have put my ability to visualise at 0 out of 10. Practice and occasional halucinogen use has got me to 2 out of 10. It causes no end of problems in day to day life, so I'm interested to hear if anyone has tips or just experiences to share so it doesn't feel such a lonely frustrating issue.
I think it's really cool you can see yourself in your mind. I was blown away when I found out thats normal. If I want to try to picture myself I kind of have to build the image, and it comes out like a shoddy police sketch of myself than anything close to a mental image.
So I can have glasses or not, because I am not viewing, I am creating. It's kind of like learning how to sketch for basics. First you make a generic face, then I add the facial features I know I have, and then come up with a generalization. But it's different every time I do it, and looks far more like a generic man, then it looks like myself.
