ANSWER: The first principle of Huna says that the world is what you think it is, so obviously beliefs about reincarnation depend on basic assumptions about life. If you believe in linear time and one life per person, then reincarnation is a fallacy and soul memories are a fantasy. If you believe in cyclic time and cyclic lives, then reincarnation is natural and dreams can be soul memories. If you believe in simultaneous time and lives as dreams, then sequential reincarnation is a very limited concept and all dreams are real. If you believe that time, space, and life as we know it are all illusions, then reincarnation is just a word and dreams cannot be soul memories.
And if you are able to change your basic assumptions according to need and circumstance, then you can believe in reincarnation on Mondays, Wednesdays, and Fridays; not believe in it on Tuesdays, Thursdays, and Saturdays; and be open-minded about it on Sunday.
