Can you dream the same thing as a stranger?

Many people say it has happened to them. Someone describes last night's dream, and it is yours, or almost: the same house, the same fall, the same feeling of being expected. People call it a shared dream, synchronicity, sometimes telepathy.

Oniraya starts from this question without answering it in advance. It is a hypothesis, not a belief: if dreams really meet, it should be possible to measure it.

Why it is hard to know

Three things blur the answer. We remember the coincidences, never the thousands of dreams that don't resemble each other. Some themes come back for almost everyone — flying, falling, losing teeth, running late: two flying dreams look alike without sharing anything else. And comparing two accounts means reading them, while a dream is often intimate.

How Oniraya measures it

You submit your account. It is encrypted, and no other member reads it. A language model derives a fingerprint of its meaning — a series of numbers — and that is what gets compared with the fingerprints of other dreams, never the text.

When two fingerprints are close enough, beyond a threshold set in advance, Oniraya offers the convergence to both people, without ever showing either of them the other's dream. They can only talk if both of them want to.

What a convergence does not prove

A measured resemblance is not proof of telepathy. It may come from a common theme, a shared book, the same season of life. That is why the measurement does not have the last word: the two people judge whether their dreams truly answer each other.

What we know today

Not much, honestly. The observatory is young, and a hypothesis is tested over time.

If you keep a dream journal, you can add your accounts: they will help test it.
