I believe this is also known as frisson. See /r/frisson for tons of media that can "induce" this. There was also an article in the WSJ that talks about what specific changed in music causes this.
The most interesting thing I found was that even by just reading the WSJ article explaining the music, I can feel the shivers.
Thanks for the links, I've tried to auto-induce the sensation with sound or images but it doesn't seem to work for me. It appears to just be a people thing.
Don't give up. It is something that can be practiced and expanded into. I've struggled with poetry, but made a recent breakthru in finding a specific author. You may need a specific "seed" to get you into that place.
