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.

This is an effect of certain Samatha meditations. It is called out of body experience. I remember reading something similar in a book by venerable Ananda Maithriya thero. He would start the meditation(Samatha) while lying on the bed and after sometime he'd be standing next to the bed looking at his body.

At one time he wandered out of the room and started exploring. Then he came to a gate/door that was guarded by a huge demon like figure. It told him something like "What are you doing here? Go back!". So he went back to the body. Later he discussed this experience with the head monk of the monastery. The head monk advised the Thero not to do that without proper preparation. Because if something else gets in while you are out, you will be locked out of your own body. People have died trying to do that.

Venerable Yuttadhammo also speaks about a similar experience in this video

No, this has nothing to do with Nibbana. You have to do Vipassana meditation for insight knowledge. But being able to sit for 3 hours and focus on one object is good progress in terms of Samatha meditation. Also, having such focus is a good starting point for Vipassana.
