wow that is so cool you met your best friend here. i was just talking to someone else this weekend who also met their best friend on this site.
haha, that is so sweet. i'm glad she pointed that out to you. i had a similar experience when i first came here in that i would read about things and realize "oh there are names for things i always thought were just weird quirks about myself".
so does that mean you have to have seen something or an image before your mind can picture it. or does it mean you totally know what something looks like but you don't see it in your head?
i am like your friend, my imagination is vivid and overactive. so it's intriguing to me to have the opposite. i love how our brains all can process stuff differently, but we also have things in common in the human experience.
