Climbling through a small tunnel...

[softie]

I've been quite claustrophobic all my life. I hate small spaces & being crammed into a space with loads of people. When I was little a lot of my nightmares, although different dreams, ended in the same way. I was sure that to get out of my nightmare I had to crawl through this tiny turning tunnel. Sometimes I would go through it & get stuck so I would end up screaming in my dream 'till I woke up. Most of the time though I wouldn't even go through it because I was to terrified of small spaces. Having my nightmares end like this made me even more scared of small spaces.
Does anyone know what this means or has had something similar in their dreams?
