Flickering Lights
Colletta had felt stifled in her friend's house. It wasn't that the house was tiny, rather it was the occupants that were stifling. Although her friend's boyfriends were skeletal monsters, she never minded that they were monsters. It was their actions that made her feel unwelcome. She had never done anything but act as a respectful tenant. When she left, more skeletons appeared as her life became a trainwreck. Old and new faces all come to ruin her peaceful life. The skeletons in her closet came bursting down the door when she didn't want them to. As each of her dark secrets becomes uncovered, she can't help, but think if she made the right wish. Warning: There will be uncomfortable topics such as abuse, violence, gore, mentions of rape, human experimentations, mental instability, terrible writing, etc. If you are uncomfortable with heavy topics, please leave. I do not wish to bring mental anguish on you. Started in: 2/20/24 Ending in: N/A
