Several weeks ago, my husband went to sleep at 9 in the evening, was still asleep at 10 am, 12 noon. Finally around 2pm someone suggested that I try to wake him up, but could not. Eventually, he could respond extremely softly to what was said to him in between garbled speech, irrelevant to anything but his eyes were glazed and looking somewhere, not the person speaking to him or closed. He eventually requested (we finally able to make out among the garbling. something to drink, but still his eyes were closed or glazed. I even fed him in the same condition. Around 6:30 pm, he awoke. He something very softly for the rest of the night, which ended at 5 am when he finally went to sleep. Five hours later, he woke up perfectly "normal", and had no recollection of the events.
When I mentioned this to his primary care doctor, he said that these things can occasionally happen with people with neurological deterioration.
I was wondering if anyone else has or had experienced this kind of episode.
