Fallen angels live forever and have been on earth for quite some time. My belief is that they can express those memories to living beings in different ways. So I would agree that you're not remembering your own past, but rather another being is telling you in a very deceitful way what might have happened back then. My two cents.
Edit: I think this easily explains how some clairvoyants can help find 'missing' items. The spirits were around when the item was originally lost and know where you left it.
