My 86 year old Mom w/ dementia lives with me. Her dementia has mostly involved her disappearing memory within a sweet pleasant personality. She loves being around her family, and our friends. Lately she's been having lots of dreams that seem to awaken her with fear, anxiety, and worry. She jolts out of a nap, and calls out for her Mother. She looks panic stricken. She's called out for others, as well. She seems to generally have gone downhill a bit. Little things, like turning on a lamp, TV, etc. seem to be confusing her more than before. Could the dreams be a sign of anything? Has anyone experienced this?
