Understand that time as we know it looks continous when it is actually experienced a page at a time. Those pages are super thin and it may well be that we actually recall those pages by jumping along a few pages at a time. Why would we not? It is also reported that a need to jump forward or backward in time is actually accomadated when it does not cause problems. Such as completing a four hour road trip often done in side two hours. This was actually treported to me by an informant who got to understand that I am thinking about TIME. This alone tells me that this is not uncommon.
