The Encyclopedia of Mental Imagery, by Colette Aboulker-Muscat et al

2,1000 visualisations you can imagine.

I initially bought this book because my friend said:

you're free to rotate a cow in your mind; it's legal and no-one can stop you

and I thought: damn, I really don't use my mind very much.

Anyway, this book is a whole other thing, it's an attempt at therapy via imagining things and breathing. And... idk, it's hokey but I'm hoping it works? I'm increasingly hokey.
