I read a few similar threads but didn't get anything out of them, so....

I read on a tutorial that we often dream of friends, family, familiar faces, ect.
This is something I don't do often. I would say I dream about my family and fiance a few times but mostly of strangers.

I know I have never seen these strangers before and they never look familiar to me in my dreams. I find it amazing that our minds can make up faces, and people with different personalties in our dreams. It baffles me that in a lucid dream, it is sometimes hard for us to do things because our mind is not used to it, but yet, we can make up faces of people and interact with them.

I also have experienced listening to music in my dreams, and performing music. Most of the time I have never heard these songs in my life. I can play a few instruments but nothing fancy, and I'm definitely not talented enough to write my own music.

I'm just curious about other people's take on this and if they have ever experienced new music in their dreams.
