Travel to the past is called retrocognition. It simply means “knowledge about the past”. This is when a person ,someway, travels to the past. A retrocognitive time traveler doesn’t wander through history, selecting interesting people or places to meet or visit. A real retrocognitive time-traveler simply peers into the past as an onlooker. Most of the time they don’t even visit places that were historically important, but peeks places or experiences of no particular significance. Here's a common retrocognitive experience, as reported to researchers Celia Green and Charles McCreery. A man named Ronald Dawson decided to revisit his hometown after a long absence. Much of the downtown area had been torn down since his childhood and rebuilt. But as he drove his car down the main street, he saw a little store where he used to shop as a child. Mr. Dawson told Green and McCreery:
I was delighted to see it and parked the car opposite. As I turned to cross the road it just wasn't there. I cannot exactly say that I saw it go, it just was not there, although I had seen it clearly.
