I can relate...mine dream pattern is always something along the lines that i am "trapped", "being followed", or unable to get out of an unknown location that i am "stuck" in." These dreams eem to occur several times a week and i wake from that type of dream several times a night but never go back into the same dream. I would agree with your assumption that it has something to do with fear. Mine i think are also along the lines of being stuck in a patten of life behaviors that i havent changed or even if i do I keep going back to.
The defination of insanity is diond the same thing over and over again and expecting a diffenrent result. Ah ha that is me!!! Why havent I been able to change all of this yet...again back to fear..... I have long been interestee in my dreams but like you stated you cant exactly give all the details tothe dream just the theme....thank you for your post.
