I was wondering about deep meditation and out of body experiences

I am very sick and as such I have tried meditating a lot, and reading about the heart mantra, as far as studying meditation. When I was meditating I was going into a trance like state for about 3-4 hours, my first question was, is 3-4 hours, deep meditation or beginners meditation? My second question was, in at least one trance state I suddenly looked down and saw myself sitting, I was out of my body, I tried to look around and I saw what I can only describe as many beautiful places/doors, Could this be any beginning to becoming realized, maybe a step in the right direction or not? Please excuse me if these questions are stupid.
