Hello AAG Attention! (lightning striking twice)
This dream suggests that there is a situation/issue which makes you feel threatened, or maybe it is mentally overwhelming. It could be that you are not seeing, not acknowledging, or are unaware of that which you fear (closed eyes) ... or maybe you do not want to see the warning signs. You are having difficulty with a transition in your life (couldn't open door), and fear that you may "crash and burn", that your newly established self confidence is going to be destroyed (helicopter).
This is a normal dream for someone in transition, like yourself. Breaking away from the old patterns in our lives brings to the surface our fears and anxieties, especially of failing, so just try to stay on course and whatever happens, don't let ANYONE take from you your confidence or self esteem, even if you do take a few steps backwards.
Make any sense?
