Nearly two-thirds of American homeowners believe that their house is haunted, according to a new survey.

The survey by Angi, a service to help people find home service providers, found that 60% of homeowners believe that they may be living with ghosts.

Of the 1,000 homeowners surveyed, more than 65% claimed to have experienced unexplainable occurrences in their homes. About 31% reported hearing unexplained sounds in the walls, 30% reported creaking floorboards and 24% reported hearing unexplained footsteps.

About 13% of respondents reported seeing or hearing the toilet flush on its own. However, Angi did note that there is a phenomenon called “ghost flushing” where toilets will flush on their own due to a leak somewhere in the home’s toilet system.

Almost 20% of homeowners surveyed said they were scared of one or more parts of their home, such as their basement or attic. Nearly 60% said they would not like to be left alone at home.

However, 58% of respondents said they would consider living in a haunted house if it meant saving money.
