Dream about being lost in a theme park indicates how you are looking within yourself to find your true destiny. You are stuck in a routine where you are doing things by rote. Your idealistic notions are deteriorating or being shattered apart. The dream is sadly an alert for death, rebirth, reflection and new beginnings. You have a cross to bear or that you are acting crossed and annoyed.
Being lost in a theme park dream is unfortunately monotony and endless repetition. You need to stop sitting around and start accomplishing your goals. You are not being taken seriously and as a result you are feeling frustrated. This dream is a clue for your disconnection from reality. There is a problem that you may not be fully aware of, but it is nagging at your subconscious.
If you dreamt about being lost in a theme park:
You may be so busy second-guessing yourself that it becomes impossible for you to make any sort of decision whatsoever. Have faith in whatever decision you make. You are better off moving forward in some manner than not moving forward at all.
