Super Power... With a Flaw

The opposite of what you dream happens, eg. you dream of having an apple on your bedside table when you wake up - you find a banana.

I can become any of my DnD characters for a short amount of time (5-20 minutes, my choice) with all their abilities, spells, items, etc.

(Since when is the opposite of an apple a banana? It should be an apple made of antimatter.)

You can appear like your DnD characters, on a piece of paper.

I can create black holes everywhere.

You do, sucking the whole universe into oblivion.

I can remake the universe you just completely obliterated, without the black holes.

you do, but the universe is now nothing like the universe you used to live in

i can create exactly twenty two cube shaped grains of sand at any point i can see in an instant

But you're blind.

I can manipulate time and space in any way I please.

but only while holding your breath. once you breath things go back to normal

I can shoot lasers from my fingers

When you do, a firework explodes 425 feet above your head.

I am the DM inside the world I am DMing.

But an evil wizard has cursed you so that the only thing you can dream about is the universe exploding

i wish i could make the world a better place. (i left plenty of loopholes there, as you can see.)

Being a Cpt.'Murrica, Shielder style, shield boomerang proficiency.. etcetc.

But, everytime he uses his shield as a Boomerang, he farts so heavily to almost break his own clothes.

i can summon Demogorgon at will while maintaining total control over him

but when you do, you cannot do anything else except maintain concentration, or he kills you.

You can see through any device in the room (computer, printer, phone, tablet, etc.)

You can't see what the screen's displaying.

i have the super power to make good, non-impulsive life decisions, and the ability to perfectly predict if an given idea will be good or bad, if an decision will be helpful or harmful and get an good (supernatural) estimation of the exact consequences of an given idea/project/decision

You lose the ability to read character sheets (in any format).

I have all superpowers, but I can only have one at a time.

Ex.) I cannot be invulnerable whilst flying.

you also have two random weaknesses, also not being able to play dnd is an small price to pay to live an good life and never make an mistake ever

One of those weaknesses is:

                    * cough at least for 3 rounds, during half-moons.

The other weakness should be:

                    * a tic that makes you scream the phrase "wree-wroh!!" every 2 hours.

OK......

*slowly backs away*

AAHHHHHH!!!!

Since that derailed this I guess I'll start it off: I can cast tasha's hideous laughter by telling a joke, but the people I cast it on actually think it's funny...

But you are also in the effect

I become my party's necromancer
