Ok, a haunted house is a money making opportunity. So consider how one explanation for the Amityville Horror is ergot poisoning: people get exposed to natural hallucinogens and can't explain why they see ghosts. Hence, to them, there are ghosts. In many dark, creepy houses that have been considered haunted, you'll probably have owners who have not been taking good care of the property. Gutters clog, water overflows over and into the walls...BAM mold problem. Here's the steps you need to take to capitalize off this:
1. Take petri dishes with you and place them in the basement, bathroom, attic and anywhere else that would potentially be interesting, biologically. Grow the samples in a controlled environment and find out if you have anything interesting. Next step, expose the cultures that you can't identify to rats, guinea pigs or your relatives. If anything has an effect, you've found your golden ticket.
2. Next, sell people the idea that you can bring back the dead and expose people who pay you big bucks to your "substance G."
3. While you have this revenue stream, find some chemist (or starving grad student) who will help you identify the chemical that makes it possible in "substance G."
4. Sell "substance G" through a network of reputable distributors.
Hopefully, you won't end up rediscovering acid. Happy hunting!
