I was thinking about this last night but I was wasted, I also like to think about astronomy and space quite alot. I don't even remember what I was thinking about but I thought "This is such an interesting subject, I want to do this at Uni"
as I said, I was wasted.
I always also think, what if this is a dream? and we're actually all in an unconscious state. What if something actually has to look after us while we're out? I just imagined that we could be dogs or other animals dreaming of being human.
