10. Omni Parker House Hotel

The Omni Parker House Hotel has a long history of sightings since opening in 1855.

In the restaurant, a painting (right) of founder Harvey Parker often projects an eerie glow, the staff said. Once, a female guest ate at the restaurant and had a frightening dream of seeing Parker in her room. As the hotel tells it, Parker appeared in front of a mother and daughter who were sleeping in Room 1012. The man in 1800s attire grinned at the girl, who smiled back. Then, he disappeared.
