I love it when I'm reading and this happens. It's like a flipped switch or something and I get so absorbed into it I visualize everything. It's almost like I'm in a trance. 

Its super jarring when I snap out of it and I have to reread a part to get back into it.

It's also really weird to explain to someone I didn't like a book because I couldn't 'watch' it lol

Saw something online where they called it "staring at dead wood and hallucinating". I love when I get into that mode.
