Does yoru dog do this? 10 points!?

My dog just stops walking and stares at nothing at random times. Her eyes go blank and she doesn't respond to me or move. She does nothing for like 3 minutes then i pick her up and take her or she runs as fast as she can to get by that area. There is never anything there but when I step into the same spot she is looking at i get chills. Is it a ghost or spirit? Or what do you think?
