Ulcer – Ulcers are a sign of stress and too many emotions. The truth is that if you are dreaming about ulcers in your sleep, you are way too stressed out about something in your life. It is highly recommended to go and see a therapist (For therapist, See Therapist). In lieu of a therapist, it is advised that you see some other professional medical staff member. Seriously, ulcers are bad enough in real life. If you are starting to have them in your dreams it just isn’t a good sign.
