I don't have Crohns, but I do have anxiety that causes me to be nauseous and sometimes throw up. It really is amazing how connected mental and physical things can be.

Absolutely. There are more neurons in your gut than in your brain, so it totally makes sense that their wires get crossed often. Symptoms in one will cause symptoms in the other. But even though I know this from a biological standpoint, it still shocks me at times

Honestly, I am so so so happy to read this because the same thing happens to me. There is not a single night I do not have nightmares and I remember every single one when I wake up. This just makes me feel like I'm not as alone as I thought. I've read it's a symptom and seen representations on tv, but they are not accurate and I do not know anyone who personally has PTSD related nightmares and understands the level of terrible these types of dreams are to live with. Thanks for just posting this.
