Indians almost all believe Bigfoot is a non-physical creature. Some Indian tribes mention that they have seen the creature transform into a wolf. Others think that these creatures live in another dimension from the physical plane, but can come here as they desire. Indians also believe Bigfoot has great psychic abilities, reports of sightings show the creature can be visible to some people, while at the same time remain invisible to others in the same group. There are many reports from non-Indians who saw the creature after a UFO sighting. And others that have searched for, and researched Bigfoot for years are coming to the conclusion that the creature is a spiritual being, because he can appear or disappear at will.

Great Lakes Indians mention that if one is walking in the woods and you hear the sound of a stick being hit against a hollow log or tree, beware, for this area is Sasquatch territory. This seems to be a interesting thing to note, because other non-Indians have even reported this. People have reported that sometimes the stick hitting is loud or thud like, like a large log is being hit against a tree, while at other times it is more like a small stick is being used. Some Bigfoot researchers have reported sightings right after hearing these strange sounds. Besides, the stick hitting, another well documented fact many Bigfoot researchers report is rock throwing. Researchers have had stones thrown at them, and at their vehicles, and there have also been reports from people living in Bigfoot hot spots, of having stones thrown on their roofs and against their homes and cabins.

The creatures episodes of hitting sticks and rock throwing may be the best evidence we have to show that they are spirtual beings. If you research paranormal cases involving 'poltergeist' incidents, you will soon realize that many of the cases involve the throwing or dropping of stones against houses, and on the roofs of the homes where the poltergeist attacks are occurring. In many of the poltergeist cases, the stones being dropped and thrown were the beginning of the infestation, or encounter, just like in the Bigfoot cases.
