The book of demons, devils, demonic summoning, and possession

It's been years since you've seen your family, but you never thought this would be how you meet again. Your father passed away after suffering a major heart attack. You are going through a box of stuff your dad left marked specifically for you. You find a book labeled " Research guide of the demonic and supernatural." Notes: Hey, very big shout out to @LewdLeah for putting in the work to create the auto card. Hey, it's getting closer to spooky day! So booo! Also, extra credit to whoever tells me what I took inspiration from to make this story. The first one will get their name on the next scenario description as a shout-out.
