This is because Slate’s childhood home is allegedly haunted.

“I grew up in a genuine haunted house.

I knew it was haunted.

The letters were apparently written by a sea captain to the former lady of the house.

I’m going to write poems about this,'” Slate said (per YouTube).

Her father brought the letters to his study which was positioned above the home’s central staircase.

Fearing a fire, Slate’s mom sent her husband to scope things out.

“He saw it but he kind of didn’t see it,” Slate said.

Of course, her dad was terrified and began looking for solutions to the apparent haunting.

A spiritually-inclined friend of the family advised them to burn the letters, so they did. "

In an interview featured in Slate’s stand-up special, her sisters talked about their memories of the house.

“It’s completely haunted,” one said.

“We’re not the only ones that live here,” her other sister confirmed.

Slate even joked, “They’ve just seen so many ghosts …

I feel like the ghosts are waiting since I’m the only one that hasn’t seen one.”
