How often does everyone dream? (Nightmares included)

I’ve been wondering if others dream often.

I don’t dream on a consistent routine but I do alot. There are times a week passes and nothing. Or small scenes of dreams that I remember when I wake up here and there but still proof that a dream happened. Then sometimes I get full blown detailed dreams back to back.

I am trying to connect dreaming to being able to travel to different realities/dimensions and I guess I wanted to understand how common it is in general for others to dream often and the significance spirituality/religion has in your life.
