I have two similar accounts but on a personal scale not as massive as what you stated.
I never thought of it as involving time shifting or moving from dimension to dimension.
When I was 8ish (1990's) my family would get together for family nights.
Aunts, Uncles, Cousins, Grandmother, Great Aunts etc...
There was a short lived trend with VHS movies where they would put the normal previews and one really really long preview 10-20 minuets.
Since one of my aunts was paranoid of ruining their VCR we never got to fast forward through them.
Anyway this one movie had one of these really long previews and the movie seemed really interesting.
The movie never came out, when I brought it up to my family they said I was crazy.
I even got the main movie and looked for the preview it wasn't there anymore.
When the interweb came about I entered as much about the movie as I could into search engines and got bubkis.
No one believes that I saw this movie preview but I did.
The other time was in HS 10th-12th grade (I can't be specific as I can't find what I'm talking about anywhere).
Anyway there was a really popular movie(everyone knows this movie).
After it came out I played a video game based on this movie, it was a sample disk for PlayStation so it had 5 levels or less.
This video game never came out, my friends who I've played this sample with say they don't remember it and that I'm crazy.
I gave up trying to convince them.
The thing is I can't find the sample anywhere, and until recently I still had every sample disk I've received.
As it turns out a video game wasn't released for this movie franchise until I was in college and it was a tangential story.
It wasn't the same story or even the same game play set up of the sample I played.
I never considered these time travel or multi-dimensional events though.
