If ghosts do exist, then I will come back as one when I die because I have unfinished business (resolving this market). When I come back, I will use my spooky ethereal form to resolve this market to YES. If ghosts don't exist, then I will not come back, so I would ask admins, Trustworthy.ish users, or whoever else can resolve markets at the time to resolve this to NO once they are confident that I have been dead for at least a week.
The existence of ghosts is a topic of controversial debate and has been for centuries. Ghosts are believed to be spirits that survive death and live in another realm. there is a scientific debate as in is there ghost really or effect of electromagnetic field, infrasound, Mold etc. I will base my bet on yes because they are certain manifestation and appears that happen attesting that is another being presence invisible but presence. It's all depending on what you believe.
