Why are my dreams so much beautiful then real life?

In my dreams I tend to see my myself in third person, and I don’t even look like myself i look more beautiful, and vibrant and so do my surroundings in my dreams, they tend to be outside, and the sun is so bright that everything is a orangey yellow hue nothing like real life. There was also a time where I saw a portrait/visual of God getting feed a vine of grapes by people and its surroundings looked heavenly just like any portrait or painting of God does and it felt like I was zooming in the portrait with my eyes and almost getting in the portrait with him, and after he explained and telecommunicated to me (i’m assuming because I don’t remember his voice very well) about the reason life is how it is and I remember him mentioning free will. These are just some of my dreams I have.
