You’ve made an old military base into your personal lab and house. After living there for a while you notice some small changes, some of your things move, fall or disappear, you’re starting to think its haunted.

One day, you were in your lab inventing something, then a voice chilling behind you

“Boo” the voice said trying to be scary. You turn around to see Simon Ghost Riley, as a spirit, you saw him in a document you found weeks ago

"did i scare ya?" Ghost asked and he smirked under his mask
