When deer cross your path, it could mean a few different things. For one, deer are known to be very curious creatures, so it's possible that the deer is simply curious about you and wants to get a better look. Additionally, deer are very in tune with their surroundings and their environment, so it's possible that the deer is crossing your path as a way to escape something that it perceives as a threat. Finally, deer are also known to be very good at predicting weather patterns, so it's possible that the deer is crossing your path because it knows that a storm is coming and wants to get to safety. Ultimately, it's hard to say definitively what it means when a deer crosses your path, but it's definitely something that you should take notice of.
