I think this is about a failed relationship. Their relationship hasn't worked and something happened to make him mad at his partner - they left him or had a big fight. So he traps his partner (I've got you in the palm of my hand) and tries to make them commit suicide with him (I want you to jump/sing/scream with me). They don't, so he kills them (the dead just like you) and then kills himself (my body's failing, I think I've hit the floor, I cannot feel anything anymore) and in his last moments he thinks how, when he is dead, he'll miss his significant other (I'm gonna miss your face/taste)
