I think it makes sense for an artist to have some kind of schtick to differentiate themselves from the crowd. And Lloyd Canning's schtick is that he says his paintings are inspired by images that extraterrestrials project into his brain. According to him, this image projection began after the aliens first abducted him in 2005. The Mirror has more details. Also check out Canning's website.
He reminds me of Flora Marian Spore, the 1920s artist who claimed her paintings were inspired by ghosts. (See Paul's post from back in 2012.)
