I keep dying in my dreams and feel the pain.?

I used to have really scary dreams for no reason. But I believe its my subconscious trying to figure things about. I remember once I went to bed with really bad cramps. I dreamt about getting stabbed multiple time in the stomach and back. Its okay. Sometimes dreams just really feel real. What you're feeling is no different from someone waking up in a sweat or screaming after a bad dream. It convinces your body its real.
