Many have experienced nightmares, but if most had it a couple of times, then the inhabitants of the castle in Castle of Nightmares had this happen regularly, so they were forced to leave it and look for another place of residence. The castle remained abandoned, and the people in the area dubbed it the castle of nightmares. Psychic Deborah and paranormal specialist Ruth decided to explore the castle and find out the cause of nightmares. Perhaps the girls will be able to figure out the reasons and even eliminate them in Castle of Nightmares, and then the owners will be able to return home again.
