Unfortunately, your intuition here is spot on. There was an abduction by extraterrestrials that took place during which all in the family were taken for a time to be studied as part of the ongoing program designed to benefit the alien Greys in studying manipulation of the human genome. So that is the explanation for the missing time and why the mother came in the daughter’s room. They were returned as a group and distributed subsequently to their original locations in the home and there was a carryover in awareness by the daughter in seeing her mother present and then noting the time. So this memory was clouded but not totally erased as was true for the time interval the mother noted.
