How can we form certain characteristics and assumptions about people we have never met in our dreams?

Question

This just got me thinking.

How is that in our dreams people we've never met smile and laugh and display certain characteristics even if we have never met them and don't know anything about their personality.

Comment please.

Thanks

Probably, if you have seen that person but have not met them and you see him/her in your dream, you have probably associated the person with another person you know and have met. Therefore, exhibiting characteristics you have no idea if Person A ever possessed because you have not met him..

If you have not met ever seen him before, maybe it was the work of your brain randomly creating another person using the attitudes of a currently known person.
