I've been able to expand my collection of ghost and paranormal quotes by spending hundreds of hours browsing old gems from centuries past on Google Books — what a fantastic resource! So please enjoy the quotations, but don't get too scared... or as they say, Mwahahahhaah

The stars was shining, and the leaves rustled in the woods ever so mournful; and I heard an owl, away off, who-whooing about somebody that was dead, and a whippowill and a dog crying about somebody that was going to die; and the wind was trying to whisper something to me and I couldn't make out what it was, and so it made the cold shivers run over me. Then away out in the woods I heard that kind of a sound that a ghost makes when it wants to tell about something that's on its mind and can't make itself understood, and so can't rest easy in its grave and has to go about that way every night grieving. ~Mark Twain, The Adventures of Huckleberry Finn
