Half of Americans swear they've previously encountered a ghost from the great beyond, leading many to believe their homes are haunted. A recent survey of 2,000 people aged 21 and over found that 63% of respondents believe in the paranormal in some form. People shared that the unexplained beings they believe exist are ghosts (57%), visitors from other planets (39%) and Bigfoot (27%). A third of respondents (35%) even said they've felt an unexplained presence in their homes, prompting them to worry that they're being haunted by the paranormal. Respondents recalled specific encounters in their haunted homes — including feeling the previous residents appearing and suddenly disappearing, hearing doors that would randomly open and close, seeing flickering lights and shadows with no discernible source. Commissioned by Phantom Wines and conducted by OnePoll, the study revealed that though 23% don't believe in the paranormal, they also don't want to provoke anything that could prove their skepticism wrong. Overall, 44% have had a personal experience with the paranormal. Two in three (63%) also believe life exists on another planet somewhere in the universe, and 55% believe full moons can make people behave in strange, different ways.
