This is probably not the strangest thing, but a chilling experience I won't forget.
It was a dark and moonless night, Zag was laying on top of his sleeping bag, instead of inside of it. He didn't like the feeling of his own body heat circumventing, slowly turning him into a baked potato. His bag was positioned on the floor of his friend's house, as they were out of town and asked his family to stay there and take care of their dogs.
Zag stared at the ceiling, not very tired but growing increasingly bored by every passing moment. One of the dogs came over to where he was, her name was Storm. She was a very friendly dog, and overly affectionate. She placed a few licks on his face before he shooed her away. "I'm trying to sleep, leave me alone." Zag said to Storm. Storm went over to her corner of the room, where her bed was, and lay down. She closed her eyes and was silent. Seemingly eliminating all noise in the house.
Sooner or later, Zag found himself drifting off into deep sleep. It didn't feel like he had slept for long when he woke up. Zag felt uncomfortable in his current position and decided to try and move. He attempted to move his arm, but to no avail. An intense feeling of panic rushed over Zag, his vision blurred, turning every strange shadow into an unknown threat. He had heard of this before, it was a negative lucid dream. As every passing moment fled, he felt as if some evil presence slowly made it's way toward him. The feeling of fear intensified, Zag was sweating now. He felt trapped and helpless, unable to move any part of his body, with the exception of his eyes and eyelids.
I'm going to die here. He thought to himself. There was nothing but silence, darkness an the increasing feeling of impending doom. Zag attempted to call for help, but could hardly make a sound, resulting in a small movement of his lips. Wait, just calm down. You know how to stop this. Zag closed his eyes, and remembered it was all basically a bad dream. The fear subsided, and Zag began to move his fingers, bit by bit. Slowly regaining the use of his arm, and eventually his body.
"That was terrifying." Zag said aloud, happy to have regained the use of his voice. He quickly went back to sleep, only to wake up to sunshine gleaming through the window.
