What a convenient example

imagine you saw this happening, pretty much exactly what you describe:

You would have seen a woman lift a man against a wall without touching him.
You couldn't explain it, because you didn't know it was a prank - so would you immediately have come to the conclusion that it must be supernatural?
A critical mind would see this and say "Well, in my experience people do not have telekinetic powers. No one in the history of humanity has ever proven to have telekinetic powers. Therefore, what is more likely:
a) I am witnessing the first ever instance of a person gifted with telekinetic powers
b) there is some kind of trickery involved and this is just a stunt"
If you choose a) without first thinking b), you should really examine the way you evaluate your experiences.
I hate the guy's pedantic tone but the information given is worth listening to:

Try telling that to the woman in this video. Her husband Ed is the only man on Earth recognized by the Catholic Church as a 'demonologist'.
Citing the Catholic Church as an authority is questionable at best
The
snopes article has some valid criticism of the couple you mention:
The truth behind The Amityville Horror was finally revealed when Butch DeFeo's lawyer, William Weber, admitted that he, along with the Lutzes, "created this horror story over many bottles of wine." The house was never really haunted; the horrific experiences they had claimed were simply made up. Jay Anson further embellished the tale for his book, and by the time the film's screenwriters had adapted it, any grains of truth that might have been there were long gone. While the Lutzes profited handsomely from their story, Weber had planned to use the haunting to gain a new trial for his client. George Lutz reportedly still claims that the events are mostly true, but has offered no evidence to back up his claim.
The Lutzes account was likely influenced by another fictionalized story, that of The Exorcist. In fact, it is not much of a stretch to suggest that The Exorcist strongly influenced The Amityville Story: Recall that The Exorcist came out in December 1973, and demonic possession and hauntings were very much in the public's mind when the Lutzes spun their stories of diabolic activity a year or two later. The revelation that the story was based on a hoax has led to embarrassment, especially among the handful of "paranormal experts" who "verified" the fictional tale. The Lutzes must have had a good laugh at the expense of the mystery-mongering ghost hunters and self-proclaimed psychics who reported their terrifying visions and verified the house's (non-existent) demonic residents.
To this day, the fact that The Amityville Horror story was an admitted hoax is still not widely known — as we often say, the truth never stands in the way of a good story. Though the story was made up by the Lutzes and further sensationalized by Anson, there were real victims of The Amityville Horror (the film, not the demons). In addition to the murdered DeFeo family, the subsequent occupants of the Amityville home have suffered a continual stream of harassment by curiosity seekers, horror fans, and gawkers who want to photograph and tour their infamous house. Then there are the people who, fooled by the films' and book's tagline, think they are partaking of works based on true events.
