Dreeaams.

Me and my friends have been talking about dreams for a few days! And It's so strange how the brain internalizes every single aspect and small detail we see. I've been thinking about it a lot lately because we think of the dreams as funny stories but when we're experiencing them its kinda like a "wow, THIS is my subconscious?" type of realization. 
Dreams are the rare ability to reach into our subconscious and basically one of the only chances we ever get aside from hypnotization or other cognitive therapies- 

I had this dream for a week or two and I couldn't get it outta my head for like three MONTHS because it was CRAZY it was genuinely a conversation between me and myself with visuals and a warning but it was like I was lecturing myself on what to do and what to change in my life!! And y'know what, I made those changes into a complete 360 and I am AWESOME, I have been so awesome. Dreams are awesome. I wish humans had more opportunities to speak to ourselves deeply in a way that it wasn't just lightly skimming the motives to our actions. 
I wonder if this is a common occurrence or just a once-and-a-lifetime thing? 
I don't see people talk about it too often. 
Thoughts?
