Lacey claims she started hearing voices shortly after the birth of her child five years ago and says they talk to her daily through the air vents inside her apartment and from a wooded area near the building.

She also claims the voices, who she calls her “voyeurs,” have been watching her and her daughter from across the pond. Additionally, Lacey says she suspects someone has “bugged” the home she shares with ex-husband, Andrew, and their child.

“I just feel like that's what I'm hearing something through, is some kind of device. I've looked through the hood of the stove; I've looked into like the heaters, but I never found anything,” she admits. Andrew also says  Lacey says she believes is there.
