Ghosts I Have Been Book

I'm more reminiscing than reviewing here, this has been a favourite book of mine for as long as I can remember. A teacher let me keep it in grade 6 because I had read it about 8 times that year. Or maybe I stole it because I couldn't part with it? That's probably more likely. Either way, that same ragged, taped-up copy has sat on my bookshelf for 17 years, with it's little "St. John's School Property" stamp inside.
For me, it's one of those stories that when you think about it, you can still remember the images it brought to mind the first time you read it. I could practically touch the clothes and smell the curling smoke. It actually gave me goosebumps and got my heart pounding. This was definitely the book that started off my love for "otherworldly" stories and opened the door to a long obsession with Stephen King and Dean Koontz types, not to mention Haunted Houses.
It's been a while since I've cracked it open now, and I'm reluctant to reread it as an adult in case I'm disappointed, but I think the nostalgia of it will override any critical thinking :)
