Because people decide to chemically jack with their perceptions.
So everyone who sees something inexplicable are only seeing it because they are jacked up with drugs? Thats what atheists claim about people in the Bible who saw strange things,,,they were all dopers.
“The Miracle of the Sun” (dopers?)

“In July, August and September 1917, three Portuguese shepherd children claimed that a miracle was going to happen at midday on October 13th. Thousands of people gathered in the Cova da Iria fields near Fátima on the day to witness the event. Estimates of the number of people vary between 10,000 and 100,000.”
“Much to the surprise of local skeptics and media, the crowds did indeed witness a strange event.”

At least 10,000 people all doped up and having the exact, same drug induced hallucination?
No, sometimes people see stuff because they are tired, or stressed, or because of lots of reasons. Not just drugs or booze they took on purpose.
I don't buy anything unless it's repeatable, and has an explanation.
