End of the world dreams

The average person thinks of themselves as a physical body animated by a soul which is a blob of consciousness which goes from body to body via reincarnation. The truth is we are magnificent beings that exist in multiple realities and realms of existence simultaneously. As we expand our knowledge of ourselves and our connectedness we experience the part of ourselves which exists elsewhere. In addition to multiple parallel universe or timelines, we exist in other realms and universes different from the one Earth is in. Time and space is an illusion so if you existed in a past reality that ended in cataclysm, you would remember it in a dream.

End of world dreams doesn't necessarily mean the one you are experiencing in this body is going to end. Your higher-self is part of the infinite consciousness that spans realities, realms of experience, time and space, past, future, present, and non-manifested possibilities. The illusion you are this body on this planet is part of the experience your higher-self needed and wanted to help it understand and process the finer points of the energy and flow of this particular universe. You are the part of the 'eternal consciousness' experiencing limit, ignorance, and mortality yet you are none of these. You actually experience a more vivid pallet of spiritual realities during the dream state including your past, possible futures, parallel lives and siblings in your soul group. The human body was created millennia ago to make it possible for soul groups that had lost their planets in wars or other planet-wide catastrophes, to be able to incarnate and continue their growth.

So, if your part of a soul group that lost its planet years ago, part of your awakening to your ancient history would be 'end of the world' dreams. You should look into the writings and videos of Dolores Cannon. She spoke of the split earth which probably occurred in 2012. In one timeline the world is devastated by a nuclear war and in this timeline, it does not. This is also a reason why some people have 'end of the world' dreams.

Don't discount these and other seemingly outrageous explanations. You are not just a human being, you are much more and your astral projections and vivid dreams are that reality leaking into your consciousness.
