Ever had a spook touch you on the shoulder when you were reading, concentrating deeply, spinning microfilm, or looking at your research work? This is the perfect time for a spook who really is an ancestor to try and contact you. And a touch on the shoulder that makes you look around is one of the classic ways they will make their presence known.
One person told me that they were struggling with trying to read some pretty difficult handwriting and had not not found the family they were looking for on a census. They were just about ready to give up when they felt one of the LDS missionaries who staff the local Family History Center, touch them on the shoulder. Except no one was there. And when they looked down to the microfilm desk again, they realized that their family group was right on that page!
