When I went to Canada in 1975 I felt that I had been there in a previous life. I found myself walking around and finding places without the help of a map. Can someone explain that please?
Perhaps the town was well or conventionally set out, the scenery familiar enough for you to feel comfortable, or you'd heard a lot about the place. There are convincing and interesting medical explanations for that been-there-before feeling. Weird feeling though, however reasonable its occurance.
You would have looked at maps & pictures of Canada at some stage before going there. Perhaps without remembering doing so.
There's nothing unusual or "otherworldly" about this.
That happened to me when I was a kid. I was with the family on a going down memory lane for my grandma's 60th birthday. We went into a town she'd lived in but was well away from where we lived and everybody knew I'd never been there. When we got out of the mini-bus I could tell them where things were. It wasn't from another life cos a lot of the things were modern and my grandmother had lived there years before so couldn't have mentioned these modern things. It's really weird. My Mum couldn't get over it!
