There was a story about a family who got a real Christmas tree that seemed to have a 'presence'. Their pets would act very strangely around the tree. They would growl or refuse to go near it. The family members themselves also sometimes felt as if they were being watched when they were near the tree. It was a very spooky situation and they ended up getting rid of the tree earlier than planned.
In general, no. Haunted stories are usually fictional or exaggerated. They might have some elements inspired by real events but are not completely true.
One of the top haunted stories is that of the Amityville Horror. A family moved into a house where a brutal murder had occurred. They reported all sorts of terrifying phenomena like strange noises, slime oozing from the walls, and seeing apparitions. It became a very well - known case of a haunted house.
One of the best haunted stories is about the Winchester Mystery House. It was continuously built and remodeled by Sarah Winchester. Legends say that she was haunted by the spirits of those killed by Winchester rifles. There are strange architectural features like staircases leading to nowhere, doors that open to walls, and secret passages, which add to the spooky allure.
