It can do things our primate relatives are thousands - maybe even millions - of years ofevolution away from, and our most complex machines are not even close to competing withour powers of higher consciousness and ingenuity.
And, oddly enough, even without any injuries or structural malfunctions, the human brain canget weird all by itself - turns out, it's surprisingly easy to trick it into seeing and hearing thingsthat aren't actually there.
As demonstrated by the guys in this 2016 Scam Nation video on YouTube, if you create asituation of intense sensory deprivation using some common household objects, you caninduce some really strong hallucinations that mess with both your sense of sight and sound.

The effects usually start to show after about 10 to 30 minutes.

After 20 minutes, the Scam Nation guys reported seeing "blooms of colour" - like those yousee when you rub your eyelids - that would soon form shapes, such as dinosaur silhouettes, jellyfish, and the Eye of Sauron.
Sounds like nonsense? Well, sure, we have to take the word of two dudes on YouTube for thisparticular scenario, but what they're doing actually follows the principles of a scientificphenomenon known as the Ganzfeld effect.
The Ganzfeld effect describes how when you're exposed to "an unstructured, uniformstimulation field" - such as seeing blackness and hearing constant television static - yourbrain responds by amplifying neural noise in an effort to find missing visual signals.
