I don't think it means we all have the exact same personality and such... Look at it as islands on the ocean. Two seperate islands seem completely seperate (islands being individual people), but they only seem like seperate things cause we can't see under the water line (consciousness), but under the water, all islands are connected... So we are all the same person BEHIND our consiousness, under what we concider "me". This is the collective concsiousness theory. Our sub-consiousness is where we are all the same person, all linked... The consiousness is our own personal view on the world, which everyone else has access to through their subconcsious... Dreams being a portal to the spiritual internet, so to speak. Suddenly we see that maybe we are not learning what the color red is, but remembering... Grasping the knowledge of "red" not from the world around us, but from the collective concsiousness... "Red" was put in the collective concsiousness the first and only time it was learned.
Things we can gain from this style of belief:
- Not death of ego, but seperation from
- Acceptance and tolerance of other people
- Comfort in knowing after we leave the material world behind, we still exist in everyone else, in the collective concsiousness
- The possibility of lost loved ones communicating to you through dreams
- An explanation for deja-vu
- Re-incarnation, in a less individual way
Things to be lost by having this style of belief:
- True identity, individuality, personality
- 99.9% of your accomplishments
- Heaven (if u believed in it)
- Creativity
