Good luck with your novel.

I'm not completely blind, but I am night blind. Lots of my nightmares revolve around me being a passenger in a car without much sight, just glare from the headlights. The fear stems from the feeling, the sensation of movement is very strong for me, falling, speeding, starts and quick turns are very clear. The driver sometimes disappears, and I've never driven, so that's terrifying. Sometimes they just become distracted and I can sense them veering.
I don't know how many sighted people dream about monsters, so I'm not sure how many blind people will have insight about that either. I don't smell things, but I do hear voices and feel the wind and stuff of that nature. Dreams that have a daytime setting have a varying amount of visual feedback. I don't see very much, faces I've seen in magnified photos are the most common.
A rule of thumb is that if a person has ever had sight, they might have visual dreams, but if they haven't, they won't.

On a related note. My father is blind and here is one of my favorite stories from him.

He dropped acid one time. Just once.
He took at and discovered himself in a great hall. I’m talking infinitely large. With an infinitely large table running down the middle. (How he knew how big the room and table were?- great question and I never thought of it until now. I’ll ask him soon.).

He heard the great booming voice of what he knew to be an angel. The angel said something like “don’t you ever do this again” and *snap* just like that he wasn’t tripping anymore.

More of a cool tripping story than a cool blind story I reckon.

This can differ depending on the sitation a person is in. A person who has been blind from birth will dream completely differently than someone who had sight and later lost it.

I'm the latter category. My dreams are very much still fully visual for the most part. I lost my sight only about ten years ago. They have always been completely vivid and too real. In fact after I lost my sight I was having confusing dreams of waking up with my sight again and my dreaming mind wourd rationalize that I was blind only part of the time, not realizing dreams weren't real.

I had sight in only one eye all my life, my sight in one was lost when I was still a baby so mydreams reflect that even today.

I have had some incredibly vivid nightmares including one where I was killed by being hit by a car and the dream continued aftert he fact where I saw my own body. Otherwise my nightmares are pretty run of the mill, being chased by things, ones where someone is trying to do unsolicitied things to me, the like.

In the end it really depends on if your character was blind all their life, or lost it later on that really determines how they'll dream.

I have acquired blindness and I love dreams because I see faces of family members as I remember them. They are detailed and focused. One good thing is that I think of them looking forever younger, even though they look like ghosty blobs now.

Also all my memories of nature like grass, trees, clouds, stars are still crystal clear in dreams.

I’m legally blind (acuity of less than 20/800 in the working eye; it’s bad enough that they can’t measure what I see ha ha). My dreams are very colorful but the focus is much more on feeling and sensation. They’re kind of frantic and jump around a lot, but usually in a somewhat linear way (well, I understand how it goes from shopping with my dead ex mother in law to being a lovesick fictional character who’s been kidnapped). I do have extremely vivid nightmares (good ol PTSD) but there aren’t usually many monsters around. There’s a lot of blood, viscera, and enclosed spaces though. Mostly it’s a feeling of dread, a presence that’s chasing me deeper into a terrible place I don’t want to be. Sometimes it’s just one nightmare element in an otherwise mundane dream (the blood pit full of teeth just hanging out in a school floor; everyone called it Steve and it was apparently friendly as long as you didn’t fall into it). And once in a great while I’ll have a sleep paralysis dream that ends with something screaming and leaping out at me from the side right before I wake up unable to move. I’ve had a few dreams wherevi “woke up” into another dream, usually with things feeling progressively worse as they went on. I’m happy to tell you more if you’re interested/it might help with your story.
