Multiple Timelines

Consider the statement, when a system is observed, its function changes. There is a thought experiment in Quantum mechanics referred to as "Schrödinger's cat." Imagine Schrödinger puts his cat in a box. The box is constructed, so the cat is instantly killed if you open the lid. The box is also constructed so the cat will be killed randomly while it is in the box. This raises a couple of questions. The first is why does Schrödinger hate his cat?

The second question is the cat alive or dead? The idea is that the cat is both living and dead until someone opens the box. ("What's in the box?") At that point, the field collapses, and the cat is dead.

When I was very young, I had a vivid dream of me watching a specific movie (My Favourite Brunette). A couple of weeks later, I saw that movie. Later on, I would occasionally experience Deja Vu. I have started to experience the Mandela Effect. Unlike remembering some future events, I have started remembering events in the past that happened differently.

This leads me to a corollary question. If other people focus on and identify Mandella Effect Events, could this result in field collapse? I have noted before that some others have talked about timelines collapsing. How bizarre, how bizarre.
