This is a wonderful post. I love that you slept through your birth! You must be a sound sleeper. :-)
Sometimes in dreams, if you talk to or befriend a monster, it will transform. I've had this experience a couple times, although there are some dreams where it's too scary to try. Maybe if you go back and face the monster, you can reclaim your sanctuary? Or go to DreamTown armed with a magic monster-slaying sword?
I had a recurring dream as a child of a devil cat who frightened me very much. I practiced in waking life facing him, so that I would do this in my dream too. Once I faced him, he stopped being devilish and simply left. The fear of cats I had at that time also vanished, and I've had cats in my life ever since.
Is there anything scary going on in your waking life that could have slipped into your DreamTown and disrupted it?
A Jungian therapist might be able to help. They work mostly with dreams and images from the subconscious and are probably the closest thing to a dream doctor. Or you might look for forums on astral projection. The people there usually have a lot of experience with otherworldly creatures and may know what to do.
I hope you find a way to return to your haven!
