My mind is really imaginative

Just had a really detailed nightmare that began where I am right now and finished in a hospital everyone was fine and I solved the crime but then the hospital was filled with horror creatures ! Then I was in the washroom putting in a Jim carry movie to cheer up. 
Woke up having to go pee. 
I'm terrified now lol 
What do you so to cheer up from a nightmare
