Good lord you're throwing schizophrenia around too freely! I'd leave diagnosis to doctors who see a person, not someone you don't know over the internet.
All of the feeling of things could be the mind playing tricks on you, if you look into certain phenomena such as the famous rubber hand illusion you will see the brain can cause illusory sensations in normal, healthy individuals.
As for locking doors, not sure the circumstances etc. My advice as with all things you think are supernatural is apply critical thinking and skepticism until you can no longer!
