Nightmares
While looking for those dreams in my xanga I came across this. I was just thinking about this very old post of mine too! Wow, I amaze myself.
For anyone else who was wondering...
During a typical lifetime a person spends about 6 years dreaming which is about 2 hours each night.
...dreaming is, thereafter, self maintained with dreamer's own thinking until the next pulse of memory insertion. This explains why dreams have both characteristics of continuity (within a dream) and sudden scene changes (between two dreams).
my favorite: While one dreams a non-lucid dream one will not realize one is dreaming. This has led philosophers to the idea that one could be dreaming right now (or at least one can't be certain that they're not dreaming).
Nightmare--"morbid oppression in the night, resembling the pressure of weight upon the breast." Such nightmares were widely considered to be the work of demons (mare or mære), which were thought to sit on the chests of sleepers.
The majority of the people who became visually impaired before they were aged 5 or 7 will have no visual dreams, but if sight is lost after the age of 7 visual imagery is retained in dreams into adulthood.
...the dreams of those who became visually impaired before the age of 5 are no different in most aspects to those of the sighted, containing perceptions of sounds, touch, taste, smell, and temperature sensations...
Happy dreaming!
