The Mandela effect is too complicated to explain to mankind, but it involves the forces of light and darkness and multi-able dimensions and timelines. Why is it becoming noticeable now Christ wanted people to question reality itself and realise the world is a lie, that it was setup to trap mankind through sin to lower dimensional kingdoms designed to feed on suffering, such is the true understanding of Hell. God and Devil are behind what is going on as a war for timeline is occurring, God seeking to give mankind the better ending as possible, though some things unavoidable, Devil seeking to make it worse, choice impacts not only your personal reality's but the sphere as a whole. A persons destination is death can be altered while they are alive, the state you die in determines what occurs when die. Sadly most of mankind got taken into Death and Hades, the underworlds and now is calling out for help to the Light to God to resurrect and free them. The narrow path to avoid this snare few found, but the good news is the Author came to fix things best that can be done.
