If you were dreaming of stomach upset or indigestion, it probably means you have consumed something that doesn’t agree with you. After waking up, did you feel your stomachache? If so, you have a real indigestion problem. Or perhaps you were hungry and your growling stomach hurt. This type of dream that is stimulated by your internal organ serves to wake you up to handle the complaint.
In dream interpretation, dreaming of stomach upset can mean something intangible that has entered into your system. This immaterial thing can be gossip. If you heard some recent gossip that is of shocking nature, and you became upset over it, then it might trigger this type of dream.
