Trying to understand

I have a question about feelings. You say that feelings don’t jump out of our body and we are the only ones that get to feel it. That I can feel love for someone while they are feeling contempt. I Understand this and agree mostly with it. However, I am curious where emotional energy fits into the model. We all have experienced walking into a room where the tension is palpable. We experience love and warmth from generous people just by being in their presence. I have experienced extreme anxiety before knowing my husband is extremely anxious. These are emotional energies that are outside of us. How does that work in the model? I truly would love to understand this.
