I just read this article as well as this one.

Very interesting showing the ways in which blind-at-birth, blind-later-in-life, and non-blind people dream and which senses are present the most.

One quote in particular jumped out at me
"There was, however, one notable difference between the dreams of the congenitally blind and controls. The blind had a lot more nightmares"
(first article).

Thoughts?
