DREAM - locking them out I was desperately trying to secure my lock to keep someone out (it was a monster or someone bad)

BACKGROUND INFORMATION: The night before the dreamer was thinking about her illnesses. She had lots of physical illness and ended up very lonely and cut off from the world. She was thinking the night before how it was impossible for her to mix properly with people. So she was destined to be on her own. This was resulting in terrible mental health problems. Locking people out mirrored her wish to cut herself off from the world.
