I've always wondered,if it was real, for example while AP-ing , if you said "I want to go to mars" ,and it was a cloudy night or you couldn't see mars, how could you go there without knowing which direction it is, unless there was some other source guiding you, that's why I think these locations you go to, are just made up in your mind. I wish I was wrong,but I don't think so. Anyone have an opinion on my logic ?
