The mites that cause scabies are tiny parasites, smaller than a pinhead. They are usually picked up by direct skin-to-skin contact with someone who already has scabies, and only very rarely from objects such as clothing or bedding.
The most memorable and emotionally powerful dreams happen during the REM (rapid-eye movement) phase of sleep, which is the stage of sleep when our brains are most similar to a wakeful state.
Sleepwalking generally occurs during the first third of the night during the slow wave NREM sleep stage. High delta activity within the brain usually accompanies slow wave NREM sleep, and when 20â50% of all activity is delta activity, stage 3 is scored.
