Whoa, not feeling pain can be pretty dangerous! I've heard of people breaking bones and chewing through their tongues withour realising it! Please be careful.

And I'm not sure if you can make yourself feel pain. I have felt pain in my dreams, but it's more like the memory of pain and it's dull and easy to deal with and ignore. I got slashed in the face once and felt the blood dripping down my face and into my eyes, and it throbbed a little but once I moved onto something else I just forgot about it.
