The first one is the process of taking food into the body and then transferring that food into energy which can then be used by the body. The second idea of digestion is less physical. This involves the idea of being able to accept some kind of information which is usually hard to accept at first. This may be because of actually difficulty of understanding or difficulty of being able to truly relate to.
If you are dreaming that you are doing a great job of digesting something it means you have had to deal with some new matters in life but you are handling them well. If you are having trouble with your digestion it means you can’t stomach this new information, it doesn’t hit you right.
You may also be having dreams about digestion because you are thinking about your own health and what you have to do to continue living at a respectable level of health. Perhaps something happened to you recently which put you on edge or forced you to think that maybe you might be getting yourself into some trouble. If you have a dream in which you see yourself having poor digestion it means you need to think about what you’ve been putting into your body lately and whether or not you are ready for that kind of responsibility. You must be committed to good health or else nothing good will come of it.
