Which species do not dream?

[gunderval]

I'm running a game in which it matters quite a bit who can dream and who can't.

That elves enter a quasi-sleep with no dreams is established. I've ruled dragons are the same.

Are there any other D&D races/species that canon says do not dream (this would automatically be indicated by not sleeping).

For example, plant type creatures and undead would not but I'm mostly interested in living creatures.

Kalashtar from eberron do sleep but they don't have dreams.
