I like to think that dreams are our brains tuning in to the many lives of ourselves across the multiverse. there are infinite possibilities, and while sleeping in this dimension, we are experiencing our life on a different timeline. the theory is impossible to prove and is a highly unlikely reality, but it's fun as hell to think about it that way
same for me and it ya it does in the sense that in waking life the brain experiences the what is(or what we think is), where in dreams we experience the what could be. the thought that we are learning and growing in this life by actually experiencing the x amount of lives we live in other dimensions while our physical self lays dormant in the one we are bound to is pretty interesting. and that our brains actually evolved to make use of that data meaningful even more so. perhaps we are experiencing but a dream of another version of ourselves when we are awake
