Yeah I quit a few years ago and before quitting I very rarely had dreams. Now I have at least one dream every night. Also convinced a few people to quit and they reported the same thing.
Did you compensate for less caffeine by getting proper rest at night? Many people quit caffeine at the same time they resolve to get a proper amount of sleep. I suspect getting enough sleep is the causative factor and caffeine intake is a confounding variable.
Wow, I never made this connection but you’re right - about the time I quit coffee my dreams started again
