The events in this book include a painting bought in New Orleans that turns out to be evil, a boy in a hotel that goes to sleep in one room and awakes in a different room after 3 days, a guy from the present that ends up at the scene of a 1920 bombing on Wall Street, a gruesome murder, a lost time event, a mirror with reflection of a person that's not there, a trailer park that might be haunted, a transplanted heart that is connected to bad dreams, a sinking lighthouse and other stories.
What is significant about this type of event is that it falls outside the cryptid/space alien genre and covers events that are just as strange but are not as numerous as the others. Quite fascinating.
