Facebook Background Check

When you meet someone online, (tinder, plenty of fish, ok Cupid, etc.) and you want to make sure they're not a total psycho before you meet them. So you look them up on Facebook to see what they post, who they're friends with, what pictures you haven't seen, etc. Sometimes you are surprised by what you find...

I was kind of skeptical about Todd, so I ran a Facebook background check to see who he really is...

mental backrooms

When you've been reading a little bit too much about liminal horror and you decide to get high, in your mind you may find yourself visiting the mental backrooms. They take a different form for each individual, but common sightings are empty places from one's childhood or recently viewed liminal spaces. Your mind is still usable at this time, but the only visualizations you see are of these backrooms. Don't worry about who you find inside. The effects last until you aren't high anymore.

I just took a tablet and all I could think of was an abandoned office, I think I found my mental backrooms! There's someone in here with me.
