A man who walked into a Canadian hospital said that he had been seeing faces every time he looked at trees – for 30 years.
The man admitted he had experimented with LSD when he was 21 – and had seen faces appearing in the leaves and branches ever since, according to Brain Decoder.
Scarily, the syndrome, hallucinogen persisting perception disorder (HPPD), is not unique – and there’s a Reddit community of sufferers.
It can affect users of LSD, MDMA, magic mushrooms and mescaline – and in some cases, affects users after just one or two trips.
It’s rare – and most sufferers just see ‘trails’, tracers behind moving objects, or geometric shapes, such as patterns appearing over curtains.
Even among sufferers, seeing faces in trees is pretty hardcore.
Has LSD affected you long term?
Get out of my head, man
Henry Abraham, an HPPD expert who has studied the disorder since the Seventies, said, ‘These people get visual information like everyone else, but they can’t shut off the noise.
‘Ordinarily, our visual system filters all of this stuff out, but theirs has a problem with dis-inhibition—and it makes them miserable.’
‘If you don’t allow yourself to be diomstracted by it, you can do OK. Those who have gotten well say the single best thing is not to focus on it.’
