ghost ghost i know you live within me, feel as you fly

The reason old buildings are "haunted" is usually carbon monoxide. That's why modern buildings don't have ghosts.

It probably takes a century or so for a ghost to manifest.

In the time span of eternity, 100 years is nothing.

I already fill that role in my household.

The show ghosts has a ghost that died in the early 2000s and he is just a baller "the pantsless ghost of a wealthy Wall Street stockbroker from the early 2000s" and he just wants to party

ooooUUUoooooOOOOuuuu Diiiiccckkkkssss ouuut for Hhhhaaaaammmbreeee ooOOOOuuuuu

"Get PWNT Noob" is written in blood on the walls. A classic late 90s haunting.

a ghost pops through the wall singing OH SNAAAKE AH SNAAAAAKE OHOOOOOH IT'S A SNAAAAKE

I'd totally buy a haunted mansion if it's haunted by a ghost from the 1990s. Hell yeah.

...Oh, I can imagine more headlines. Someone spending a lot of money to buy a house haunted by a communist, and the sociopolitical debate this purchase creates.

"Rawr XD" why not "Rawr X3"?

They haunt the abandoned malls and apartment buildings rather than old houses...

I'm pretty sure my ghost is still partying with the goths, in the loft I lived in in 2010.

If you start seeing phantom CD cases with lines of speed racked up on them, or hearing the faint sound of epic mashups, you'll know you're in the right loft.

The causes might be environmental.
Haunted houses are a product of the US culture and the oldest houses commonly in use there are from the 1700s.
But it also needs to be fairly isolated - nobody is going to notice a haunting in the middle of a city.

I would immediately find an exorcist to banish that bitch.
