Ghost or Time

There has been alot of buzz pertaining to the Birdcage here in New Mexico. Is it really haunted? The paranormal investigators known simply as TAPS seems to believe it is. Now I really respect and somewhat admire this organization. However when investigating the paranormal I believe one must be able to disprove the known science first before being able to call something paranormal. Whether it be a place or an entity.
In Science there are events known as time rifts. Imagine if you will that time is a straight line and for whatever reason time loses it's ability to be able to keep the line pulled tight, if only momentarily, what would be created is a temporary gap thus allowing the present to see the past. Further imagine if you will a woman sitting on her porch who suddenly upon looking in her backyard sees a group of little girls jumping rope and laughing. As she gets out of her chair to investigate the group of girls disappear. Did she really see the girls or did she see ghost? Perhaps neither. Perhaps she saw a moment of these girls past and as she went to investigate time pulled the line straight making the image disappear. While I do believe in the supernatural all possibilities must be considered. Another possibility is what's known as echoes. If the house or land has the ability of projecting memories then the actual spiritual entities ,those girls, are not a factor, the house or land just my be projecting images and even sound to relay the overall disposition of it's last owners or events. If the woman actually investigates all the previous owners she may come to find that one or more of the girls she saw are actually alive, thus disproving that what she witnessed was ghost. Investigation is vital. I guess all one can do is watch out for cold spots and take EMF readings. Also check the history of what your investigating. Above all consider all possibilities.
