Weird emotions/feelings that don’t feel like mine. Anyone else ever experience this?

Hello everyone, I’m not exactly sure how to describe what I’m feeling but I’ll do my best. I feel like there’s too much energy (not that I have too much energy) trapped inside me. It’s almost like my whole body is buzzing and it’s really uncomfortable. I generally look for reasons first but I’m healthy, I am not upset or feeling bad myself nor is there an identifying trigger, so I don’t think it’s emotional or anything like that.
