I can see that without smoking. haha. But yeah I knwo what you are talking about. A really trippy thing that happened once after I took 24benadryl pills I saw myself in the mirror. And I could see my heart pulsating. And the mirror me was moving and talking to me. Then spiders started to consume my body till I passed out. Anyways when I close my eyes I can see outlines of shit, but I think it's memory.
