reincarnated as my sans au [Obsessed Bad Sanes X Sans!reader]

Introduction

Darkness...That's all I see. Just an empty black void. What happened before this? Memories, They're coming back to me. I've been killed, no, murdered! By my best friend. He invited me to a party he wanted us both to go to. "Hey when do we get to the place?" I asked."Oh! Not too far just one more minute..." He said. After a minute of walking he stopped. "We are here." As he pulled up I saw what looked to be a mansion. As we walked in I started looking for the party. "Hey, you sure this is where the invitation said? Not to be rude but it looks abandoned." I tried to turn around, but before I could fully, I felt something collide with my head before the blackness took over my vision I saw a bloody bat that was held by my friend.That's all I can remember before I was trapped here. How long has it been, hours, days? I don't remember, its kind of hard to tell time. it feels weirder, slower yet...faster at the same time. before I could finish my thoughts all of a sudden im engulfed in bright light. Guess i'm going to the afterlife...
