Central City Colorado Springs and Mesa Verde Hauntings

I love going over to Mesa Verde in the southwest area of Colorado. There are many of the Anasazi ruins that you can walk through. The feeling you get when you walk inside the ruins where these people lived so long ago, is amazing. Many people have heard whispering in a "foreign" language, and have seen spirits of the Anasazi inside the ruins. Perhaps this has something to do with the fact that each of the ceremonial buildings has a hole in the floor that is a spirit gateway?
