A man who was an alcoholic had an experience. Alcohol is not a halucinagin,but various compounds can enhance brain activity.Not hurt it at first,but enhance it. Many artists use it.Medicine men used it.Musicians,ect. This poor fellow was made famous by claiming he was visited by pink elephants.He did not think it was funny,he was not stupid,he lived in the big city. He was sent to a psyciatrist.The psyciatrist blamed it on his drinking and laughed at him.He betrayed this mans confidence and told all of his colleagues,and so on. "But I touched One!!" he pleaded. People near death, or overdosing,have mystic experiences,sometimes changing them forever. There are being out there,not in the physical,that exist with us,here,not on some planet. Call them friends and neighbours. This man was scared out of his habit I assume. I have had visits from these illusorary people all my life in times of crises. Yes,they can appear as pink elephants.They can also appear as angels or demons. Not magic actually,just screen technology way in advance of us. Simple really.We think we know it all,they have delight in showing us we are alone or the masters of this world. You think these beings look rediculous? When seen, they send most running off screaming,they are so strange. So accept the projected images for now until you are ready.
