Do people live from dreams?>?

alright/ this is a bit manic.. im gettin a bit dream obsessive.. if you don't dream when you are under 9/ do you gradually built more information/and dream more as you age bc your brain gets more activity? and also/in dreams a lot of things seem to be going on/ in short periods of time/since your brain is highly engaged.. in real life/ i find myself in moments where i think to much/ and time appears to have gone by slow.. are our dreams ques how to live our lives when we are awake? or just an escape/ or form of entertainment? i feel like they give you cues on what to do/ and maximize your human potential.. that is if you have enough time to pay attention to those dreams and in waking life..
