Still with that fear or stress over being forced to change and that the change is going to harm you. The imagery is basically the same message as the being pushed ones. As for the pressure around your neck, what position are you in when you wake up ()face down/on your side/any weird limb positions/etc)? It could be that you tuck in your chin in your sleep...or it could be that you tighten your esophagus in your sleep...or (fi you're sharing a bed) it could be that your bed partner attacks you in THEIR sleep (my wife used to do this to her ex-husband in her sleep) :P
