To dream of a sandwich means that you have some sort of pressure or stress on you in your waking life. Perhaps you are trying to get through a particularly difficult situation right now and are feeling the weight on your shoulders.
If you dreamt of a sandwich that was cut in half it could signify that you don't want to deal with whatever problems you have all at once- you want to take things one bite at time.
If your sandwich was lined with peanut butter, something generally thought to be a food for children, this can indicate that you are attempting to be carefree about your problems. You are trying to avoid the importance of something in order to get through by burying your head in the sand.
Furthermore, if the sandwich had jam inside- one interpretation is that you are engaging in temporary pleasures and diversions to help you to cope with this situation.
Another point of view is that you have been thinking about your basic needs of late. Maybe you feel your primary needs are not being met by you or someone else.
Finally, another thought process is that you have the potential to fulfil an ambition of yours- but first you need to assess the levels of opportunity that are available and what they mean for you.
