Energy shift 

There are many things you can pick up just by being in a close setting with other people. 

Negative energy 

Negative emotions 

Have you ever been in a place for hours, and your energy starts to feel drained?

Were you ever in a fantastic mood, and all of a sudden your mood changed after going into a place where the energy was not so good? 

Were you ever around a sad person, and did you pick up on their energy?

You have to be mindful of energies that are not yours. You may start to pick up on someone's energy and not realize it. As soon as you notice what's going on, do something about it. Change your thoughts to positive ones. Listen to some uplifting music, or go for a walk to clear your mind and remove any negative energy. This will help improve your life by simply learning to get rid of energies and emotions that are not yours.
