re: Ever had very detailed dreams of persons you’ve never met? Or even recognized?

It seems like it would be easier. I know I've had songs or riffs stuck in my head that I've never heard before and when I woke up I grabbed my guitar to try to get it down. Our brains seem to be creative machines when dreaming or in altered states so I don't know why we couldn't create faces, voices, personalities, etc. At least that's my ignorant amateur opinion
