From my experience I am beginning to speculate that hanging out with groups of people leads to more lucid dreams. The other night, after coming home from a party (when usually I tend to lead a mostly solitary existence) I was having lucid dreams all night. And now that I think of it, the one time I had lucid dreams for three nights in a row was the time I was sleeping over at someone else's house, having spent the days spending time with more people than usual. So, has anyone else ever come up with, or heard of a theory that being around crowds of people at night increases the chance of having lucid dreams?
