Dreamtime - The dream of the man in prison for shooting someone seems a straight representation in dream language of 'what you sow you will reap'. It suggest that at some time you must have said or done something that hurt someone - dreams often use 'shot in the stomach' to represent things said or done that causes the person to feels as if they have been punched in the stomach - but it doesn't show on the outside, because there is no bullet wound.
The black hole can suggest that you have been imprisoned by your own interiorised hurts or feelings, opening you to your core self - the hole. See
http://dreamhawk.com/dream-dictionary/core/Touching your core self may have left you feeling as if you are losing a sense of who you are. That is a natural process of growth because internally in our deepest self we are not the personality we developed as we grew from childhood - we could have been anything, but where guided and shaped by circumstances. But of course your dream shows a complete loss of you memory and identity because it is suggesting that you - a part of you anyway - will now develop a new way of living and being. See -

http://dreamhawk.com/dream-encyclopedia/autonomous-complex/The third dream carries the theme further. It shows that you, a creature that lived in water - in your mother's womb - has now starting a new life guarded by the great force of caring Nature - the mother elephant. You are still partly in the waters again - mostly likely because often we have to go back and live the past stages of development again because they didn't work out to well for you the first time around. This time the Great Mother is protecting you against the cold world so you can grow successfully this time. So be patient with yourself as you pass through the stages of growth. Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.
Nicodemus saith unto him, How can a man be born when he is old? can he enter the second time into his mother's womb, and be born?
Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God. That which is born of the flesh is flesh; and that which is born of the Spirit is spirit. (The gospels are all about the inner world we find in our dreams.)
You are on the verge of discovering what many seek.
