In your dream, death represents change. Your bed, in your home symbolizes the place in your mind where information, or knowledge, can sink in. In other words, as you experience and learn new things, your mind needs time and a way to absorb this knowledge. So, dying in your bed at home indicates that your ability to absorb new information has changed. With your stated health issues, you may be overwhelmed with health related thoughts and information, that you just simply shut it out. Another reason is that you are too tired to be able to relax enough for knowledge to sink in. Animals represent habits, and your pet is a habit that you are warm to...one that you favor. Habits are those things that we do without thinking. The food we eat, the clothes we wear, the way we act or react toward people or things. It is within this habit that you feel somewhat safe or at least for the moment, free. With the inability to let information sink in, it makes sense that you find more comfort in a pleasing habit. Look over your life and see where you are distracted, tired, or otherwise finding yourself running on auto pilot. Try to gather the courage and strength to 'sink your teeth' into something that requires concious thought, followed by some kind of action. Hope this helps in some way. I pray for your peace and healing. God bless.
