I Have An Overactive Imagination

I have more of a constant imagination and a very random one. What happens to me is that whenever I hear or even think of something, my mind automatically start to imagine it. So much so that sometimes my mind replicates the appropriate senses. But the strange thing is that when I am in this brief day dream state I can still process and see what is happening in real life. Also rather often when I close my eyes for just a few seconds or if I just bl<x>ink I see the most random things. It can be anything from an interesting design to a monster ridding a hippo with a too too that is running through the sun.
