I had a dream a few weeks ago in which a monk of some kind told me

"The purpose of dreams is so that those who have already lived in this life can reach enlightenment without having to."

I've had a few people try to interpret this but its kind of a confusing statement because we don't know what the "without having to" refers to. I'm guessing living in this life. My friend's friend said that it might be about learning through experiences of our past lives in dream, without having to really experience them again in this life. I haven't really made up my mind. Any thoughts?
