I read an interesting article that animals (not just people) have spiritual experiences, according to a prominent neurologist. Research suggests that spiritual experiences originate deep within primitive areas of the human brain — areas shared by other animals with brain structures like our own.
"Despite this limitation, it is still reasonable to conclude that since the most primitive areas of our brain happen to be the spiritual, then we can expect that animals are also capable of spiritual experiences," added Nelson, author of the book "The Spiritual Doorway in the Brain."
"In humans, we know that if we disrupt the (brain) region where vision, sense of motion, orientation in the Earth's gravitational field, and knowing the position of our body all come together, then out-of-body experiences can be caused literally by the flip of a switch," he said. "There is absolutely no reason to believe it is any different for a dog, cat, or primate’s brain."
