Episodes going on and I don't know what to do.

This is all going to sound weird but its bothering me. In January I started having issues of having the chills or my hands/arms shaking out of control. This didn't happen every nite actually seldom but now they are getting more frequent . Its usually when I have been sleeping. These episodes don't last long but I can't stop them. Last nite I was watching TV and my one arm started shaking and then the other arm did and it lasted awhile and I was thinking how do I stop this , it finally quit. One episode was my heart was beating so fast and so hard and I was breathing in very deeply. Didn't last long and it quit. Today now I have a headache and earlier I would just fall asleep, start dreaming and waking up when I was talking aloud to someone in my dream. Those dreams are so real. Been thinking I should make a appointment with a neurologist but don't know if I should do it now or if I can wait until I go back to mayo for a ct scan for lung cancer in late June. Any ideas...… or am I just weird. My blood work is good, except my thyroid was a little off , first time , always good before.
