It's something you've created. The mind is the most interesting place, but it's not really a place.. is it? And you can never go to someone else's, no matter how well you know them. There's no such thing as a secret inside your own head, only organized information and the truth for what it is. Some people can't sleep at night, because what's in their head is so drastically different than what's on the outside. Playing games with your own mind is boring, i'd rather meet other people.
I could retreat to the dreamland in my head for hours and days at a time, but what's the point? Perhaps for creativity-sake, but other than that I'd rather be outside.. in my play clothes. (wink)
