I hate to break the fourth way, but I am truly fascinated by this phenomena.
Was this in earnest, or in jest? Does it really? I knew someone who was like this and it blows my mind in absolutely the most fun ways. I'm not trying to be 'weird' so I understand if you don't want to discuss it, but like... serious.
I and absolutely fascinated by synesthesia and would love to know more about it.
