On the page here, we read this:

" A new YouGov poll asked Americans about their paranormal experiences. Most Americans say they’ve had at least one paranormal experience, and many believe that they personally have a paranormal ability."

The poll was a survey of 1136 American adults. Among the more interesting findings were these:

• 50% of the Americans polled believe that some people have paranormal abilities, much higher than the 28% who said they do not believe people have paranormal abilities. 
• 18% of the Americans polled reported "seeing unexplained orbs of light."
• 16% of the Americans polled reported "seeing a spirit or ghost." Of these, the majority said they had seen such a thing more than once.
• 23% of the Americans polled reported "seeing lights or other devices turn on or off without explanation."
• 17% of the Americans polled reported "seeing an object move without explanation."
• 16% of the Americans polled reported "seeing a door open or close without explanation."
• 59% of the Americans polled answered "Yes" to the question "Do you believe that there are people other than yourself who have had paranormal encounters that cannot be explained scientifically?" This was much higher than the 21% who answered "No" to that question.
