Something I've learned about dreams... though this may just be personal experience talking...

Dreams may feel like real life... but real life never feels like a dream.

However, when I dream, I see perfect details on people's faces if they are people from my waking life; I can feel the wind on my face when I fly (the air even gets colder and I can feel the moisture from the clouds); I can smell scents; feel the exertion in my legs when I run...

Dreams have this incredible ability to feel very real when we dream them... partly why it's so difficult for many of us to realize when we're dreaming!
