It sure is. I believe we have at least a limited ability to sense danger in some forms.
Once when I was 9 or 10 my entire skin crawled and my hair stood up. I turned around to see a really creepy looking guy staring at me. Made a quick exit for sure!
Years later the same feeling hit me during a hike in the woods and I looked behind me to find a bear, staring at me like it couldn't decide whether to kill me or just let me have a heart attack and die on my own. It just stood there and I backed away slowly as I'd been taught. I picked up the pace as soon as he was out of sight.
Both times I didn't hear or smell anything.
