Whilst on holiday, me and my fiancee were out for a stroll in the late evening. We were walking in a quiet residential area where peoples' villas are surrounded by walls and a gate. We were having a nice chat when all of a sudden a dog on the opposite side of a gate barked furiously making us both jump. I immediately got into a kind of half stance with my hands in position for a fraction of a second until I realised it was just a dog and there was no threat.
Is the fact that I jumped, a signal that I am not fully aware of my surroundings?
I'm asking for peoples opinions on if you can reach a state of awareness where such instances would not make you jump but you would still be aware and prepared to react efficiently to a potential situation. Is being jumpy a signal that you're ready to react or that you aren't aware?
