Wow, are you me? I also experience this specifically. The hallucinations tend to be "spiders" or intruders (spiders in quotes because they're more shadowy and ephemeral than your standard tarantula) and incidentally, it's been "ramping up" for me lately, to the extent that it's a pretty dependable, nightly occurrence. I too think about it a lot and worry about the early-onset dementia angle. Do you have any conditions in the broad spectrum of "anxiety" disorders? I've had a pretty rocky relationship with my sympathetic nervous system; variably severe anxiety, some panic attacks, occasional bouts of depersonalization/derealization. It seems pretty likely that these symptoms spring from the same root cause as the "night terrors." Fortunately I'm not personally aware of a link between these issues and dementia, though I wouldn't be surprised if someone replies with a link to some study that ruins my day.
