I suppose it's impossible for me to "prove" whether these memories were/are more-or-less accurate. However they're self-consistent: since this phenomena emerged I've been recording my experiences and the referenced details within the dreams have remained unchanged. The circumstances also map correctly to knowable context: in one of these dreams, I was traveling for work and staying at a hotel. I have the email confirmation from that hotel, and a note from the same day with a simple remark about that lucid dream. Beyond this, I feel a deep, unshakeable confidence that this experience of recollection is unmistakably true. Who knows?
