The timelines intermingle and the division between the adjoining universes thins and permeates events and information. I have experienced my own personal Mandela effect, generally with objects that I clearly remember have been irretrievably damaged, I have thrown them away, and later find them intact; or with objects that I have bought and there is no way for them to be lost, due to their size, and suddenly it happens that they never existed, this happened to me with a vacuum cleaner that I gave my mother on a trip I made to her house years ago . So it is undeniable that this exists; but I think it is much older than 4 years. Greetings and blessings.
