Since alcohol has a profound effect on the mind, I'm wondering if it also has an effect on dreaming. I'd say I'm a moderate drinker, and I've found that nights I drink tend to go by more quickly and be relatively dreamless. I don't know if it's a direct effect of the alcohol or the fact that it makes me sleep more deeply or what. But if it does have a negative effect on dream vividness, that would be a great reason for me to quit altogether since I'm trying to get on the lucid dream track now.
