lol, no idea, did a google image search for "pink aliens"
And yes to the out of body experience thing...
The whole logic behind the pink aliens thing is from a dream I had a long time ago, or recurring dreams... I fell through a hole in a tree that had a portal to another planet full of pink people, that needed help with their computer, and they lived in domes in domes in domes, with a pink sky and there was something really scary outside of the domes...monster like I think....
Always stuck with me... Was the theme here...
