Yeah, I wish I could fly or run at super speed or teleport. Whose doesn’t?! But the superpower I crave most acutely is the ability to dreamwalk.
There are innocent uses. You show up in your friend’s recurring nightmares and tell her that this time, it’ll be okay – she’s safe, her dreams are made of dust and fantasy, and she can control them. You chase off the monsters and demons and teach her how to turn lucidity on and off. She can rest easy without your help.
But oh, god, you can also make the person who gave her those nightmares in the first place pay for it. Sleep tight, shitlord! What’s the matter? Did you have a bad dream? Are you ready to have bad dreams for the rest of your life? I hope you like sleep deprivation, asshole, ‘cause I’ve got a full tank of nightmare fuel and you’re riding shotgun.
Corrupt politician ready to vote for an evil bill? He can’t prove that you terrorize his dreams! Maybe he’s a rich bastard who will never experience any of the horrible consequences of his actions first hand…but he’s a rich bastard who wakes up screaming every night because The Ghost of Christmas Fuck You has come a-calling.
Honest to god this is so close to my mood right now I am cackling. Holy shit.
Dream is honestly the most underrated spell in D&D. I mean, think about it. You wait for your enemy to fall asleep, and bam! Take 3d6 psychic damage, a CR 3 Nightmare, and a level of exhaustion. You can literally torture someone with a low Wisdom save to death in their sleep across the course of a week.
Players, if you want to seriously screw with your DM, use this to have your PCs torment the BBEG. DMs, vice versa.
