I don't know about it being a quantum system, but from a psychological standpoint our memories are definitely shaped by the way we perceive and process an event. There was an article posted on HN recently about why we don't remember being babies - some think that language is required for forming memories. The way a shared memory is remembered and re-told by other people (i.e. parents) can also affect our own memory of it.

As a person suffering from social anxiety, my brain tends to memorise events by focusing on small, irrelevant details - which leads to negative self-talk, i.e. "was this thing I said embarrassing? could I have done this differently?, etc."

The way we perceive the world and store our memories is definitely different from one person to another. As a bilingual person, I think some of those differences may indeed be due to a person's native language.

If language is required for forming memories, surely babies that have learned sign-language would remember something, no?

As a bilingual person, do you dream in both languages, or one particular language?

In my case after living in another country for about 3-6 months I've started having dreams in new language. It came more less together with having inner dialogue in the head in new language. New one replaced the old one.
