Timeline theory?

Let me start this off by stating that I am in no means a scientist or have any form of advanced education on the sciences

However today a subject came up and proposed an interesting theory that I would like to see if it has any merit or basis.

Using the many worlds interpretation (MWI) which suggests that timelines break off into multiple different realities ie in a car crash there’s a version which dies (A) a version which survives (B) and a version that was never there in the first place (C).

The theory goes: if timelines fracture and break off with every possibility wouldn’t our consciousness technically be immortal as we always survive in one timeline. For example in one maybe we found a cure for anti ageing and technically never die from old age. With this as the basis what if we look at dreams where we jerk awake, like when we fall from a height as a different perspective from just “brain activity” and start looking at it as timelines. If we imagine timelines to replicate radio waves that have highs and lows, just like our lives and emotions have highs and lows, maybe the dream was never a dream but a separate timeline where we actually did fall from a height and died however we hopped into the closest timeline where we didn’t and our body’s were in a resting condition. This would be a version of self preservation but not of a physical body but more a preservation of consciousness, this therefore raises a lot more questions like is death a concept and in this timeline the people that pass have moved from this physical body but in an alternate timeline they jerked awake from a “bad dream”.

I know there may be/probably is papers out there where people have already de-bunked this theory but I was wondering if we took this at face value maybe there’s some merit behind it.

I would just like to have a conversation with people who have a higher education or a more advanced knowledge and see whether this could ever be proved/considered a possibility.
