very odd

So I was reading about Mary Magdalene (long story as to why, completely non- religious reasons) and for some reason I had a tightening of my chest, and all the physical sensations of being upset and crying without the emotional side of it. I was not upset, but my body was reacting as if i was :S

So i clicked onto facebook and it stopped, then I resumed reading about Mary and theories about her relationship with Jesus and it started again. Tightness of my chest, light headed tears forming in my eyes, a tight throat...

So I looked into the mirror to see if I was crying and my eyes were filled to the brim with tears but as I looked the tears were reabsorbed by my eyes, my eyes became white again (rather than the red swollen tinge of crying) and my face went back to normal from being red. This happened in probably less than 2 seconds of not reading the passage.

What is going on?
