Cambridge Coincidences Collection

Well I Never!

Professor David Spiegelhalter of Cambridge University wants to know about your coincidences!

Why? By recording your coincidence stories here, you can help him build a picture of what kinds of coincidences are out there and which ones seem to ‘get to’ us the most. Your coincidence stories can also help him explore the scientific explanations which may account for them – whether by doing the maths to calculate the chances of a coincidence, or speculating on the weird and wonderful workings of our brains.

Coincidences tend to be ‘surprising matches’ – sometimes they are lucky, sometimes unlucky, sometimes just mind-boggling. To help you recall the coincidences that have happened in your life, here’s a list of some common types of coincidence:

  • Surprising repetitions: for instance when you’ve had not contact with someone for ages, then find two connections to them very close together in time. Or when over several years multiple members of the same family are born with the same birthday. Or even a repetition of a really rare event – like winning the lottery twice, or your life being saved twice by the same person!
  • Simultaneous events: for example when two people phone each other at exactly the same time.
  • Parallel lives: such as when two people in a small group find they share a birthday or an unusual name, or when two people discover their lives match each other in bizarre details.
  • Uncanny patterns: imagine picking letters in Scrabble that spell your name.
  • Unlikely chains of events: perhaps you lost your false teeth overboard and found them inside a fish you caught twenty years later?

If anything coincidental has happened to you - anything that made you stop and say "well, what were the chances of that..?" - then please record your story in the form below! Please try to keep your story personal - about you or someone you know. The only thing we'd ask you to steer clear of are premonitions or déjà vu, purely because - whilst fascinating - they're quite common and also difficult to analyse.

You could also tell us about coincidences in the news, but please provide a link to a reliable source!


Title: two or three words that give a simple description of your story, eg ‘old friend’ or ‘birthday coincidence’
Coincidence: tell your coincidence story - and please include plenty of relevant detail (places, dates, numbers etc.) and include your first name if you want.
Email address (optional): please leave an email address, as then we can get in touch to find out more!

Hyphenation coincidence

On 2 October 2016 I was reading a book (Critical Assembly - A Technical History of Los Alamos during the Oppenheimer Years, 1943-1945). I read the last line of page 117: During the summer of 1944, however, 3-inch testing became less de- I turned over and continued reading: cay series, is ordinarily isolated from lead concentrates. Although en- I realised that this did not make sense. I then discovered that I had turned over two pages, and instead of reading the top of page 118, I was reading the top of page 120.

The Scorpio.

10 years ago I was working for a company but I did not like my job. I started considering to go back to University to attend a Master degree. But this would have meant to quit the job and to use all the savings I had. My partner suggested me not to be silly and to keep working. In his opinion I was going to leave a certain future for uncertainty.

Everything Comes in Perfect Timing

So my coincidence is more like a series. It is January of 2019 scattered with synchronicity after another all centered around this one person. I met this guy over the summer, moved away, moved back and he was dating someone. Then we reconnected at the beginning of January through a mutual friend who I met 5 years ago at a hostel and was back in nola visiting his partner who just moved here. This guy was roommates with my friends partner...so we reconnected and found out that he was going to be at a tree planting my nonprofit was organizing two days later. Great so saw him at the planting.

Synchronicity of words

My story is very similar to the person who wrote about reading a word (and the same word is said at that moment or one second later). This happens to me almost daily, as expressed by the previous writer- from 2017. Does anyone know what this means? Please write me back, a comment/information, Thank you Sagacious11

Movies and Coach

A. The Wizard of Oz (1939) 1. Hickory, North Carolina, is my hometown. I graduated from Hickory High School in Hickory, North Carolina. The mascot for this high school is the “Red Tornadoes.” I am not sure what year this high school adopted this mascot though the Wikipedia page for this high school does state that the high school in Hickory, North Carolina, was renamed “Hickory High School” in the 1940s. In the 1939 movie The Wizard of Oz, a tornado sweeps the character Dorothy Gale and her dog, Toto, away from Kansas, and “Hickory” is the name of another character in that movie.

My moms death and anniversary

My mom passed away April 2, 2017 from a brain aneurism. The previous day I was at her house picking up my son. I dropped him off with my husband then went to work a graveyard shift at a coffee shop. The regular coffee drinkers were telling me about the guy that bought my old house which my mom gave to me but my husband and I returned to her so she could sell it. They told me he hanged himself in the backyard. I thought they were playing an April fools joke on me but they kept saying nope it’s not the first anymore. I got chills and was creeped out. I left work at 5am.

This is a double coincidence almost...its weird.

My name is Tully. Very weird name, I know. There was a movie that came out in 2018 called Tully and it instantly piqued my interest because I am literally the only person I know with such a name. I then looked into the movie, trying to find out why it had the same name as me and then discovered that the actress who played Tully, Mackenzie Davis, was born on my birthday. I was born on April Fool's, so not exactly one of the common ones and to this day it just boggles my mind.

The Appalachian Trail

As Ralph was leaving for some researches in the Harvard Library, his psychic girlfriend Betty told him that something important would happen at 2:00PM. Indeed he stumbled walking down a stairway at that time, and Susan, who was walking up, came over to help him pick up his papers and books. Grateful for this help from a stranger, Ralph suggested they go for coffee.

My friend's son in Thailand

I talked to a friend of mine in Maryland and told her that I was going to Thailand on a trip. I told her that I owned a condo there and would be staying for several weeks. She said "Oh, that's great! My son is in Thailand now.
