Fiona BroomeThis website is a project of Fiona Broome. That’s me. I’m a paranormal investigator with somewhat renegade ideas.

The “Mandela Effect” concept emerged from one of those quirky ideas.

Many of us — mostly total strangers — remember the exact same events with the exact same details. However, our memories are different from what’s in history books, newspaper archives, and so on.

This isn’t a conspiracy theory, and we’re not talking about “false memories.” Many of us speculate that parallel realities exist, and we’ve been “sliding” between them without realizing it.

At this website, we’re using discussions to research real, alternate history and possible explanations for this phenomenon.

Here’s how this website began:

Many years ago, I was one of the two people who coined the phrase “Mandela Effect” during a conversation in Dragon Con’s “green room.” That’s where invited Guests and event speakers gather. (The other person was Shadow, then a Dragon Con security manager.)

I think this started in 2006,  I’m not certain of the exact year. It may have been as late as 2010. Our annual get-togethers have always been odd and interesting, and involve weird topics like this.

In the “green room,” between my personal appearances at Dragon Con, security manager Shadow mentioned that others (besides me) remembered Nelson Mandela dying in prison.

Apparently, others in the green room shared that memory.

For hours after that, a group of us — mostly authors — discussed our memories of Mandela’s death. Soon, the conversation included other events that don’t match the timestream we’re in now.

After that, I researched the concept and — with my publisher’s support — started this website for additional research. I thought it was an interesting fringe topic (and potential book topic) for my spare time.

It’s turned into something much bigger.


1. What is the Mandela Effect?

It refers to apparently real, alternate memories of a history that doesn’t match the documented history in this reality.

2. What causes the Mandela Effect?

We haven’t a clue. Right now, it’s all speculation. See the Sitemap for my related articles. Also, many of the best answers from this community are in comments at the Explanations page.

3. Why are some comments out of order?

This site uses WordPress and some related plugins. With the high volume of comments at this site, the software sometimes loses track of which reply belongs with which comment. And, sometimes, people forget to hit “reply” and just post a comment… that’s added at the end of the list on that page.

4. Why don’t you use a message board?

This isn’t a social site. It’s a blog for research-related conversations, documenting credible alternate memories and how science — especially physics — might explain what’s going on. We also talk about historical references to time and dimensional travel that may relate to the Mandela Effect.

5. What are “markers”?

Short answer: At the moment, we’re using the term broadly. Markers seem to be indications of a reality shift. Other than that, we’re not sure. They could be deliberate signs (sometimes, literally) that indicate access points or portals to other realities. They could be coded messages.
