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.
Sleep terrors are different than nightmares in that they occur during non-REM sleep, while nightmares typically happen during REM sleep. Sleep terrors usually occur early in the night and can include arousal, agitation, large pupils, sweating and increased blood pressure for the sleeper. The sleeper typically does not remember the dream by the time they wake up[1].
