In the dream I am within my own body and feeling sensation, but I am also (simultaneously) seeing myself from a third-person perspective. Both perspectives, although clearly me, seem to be separate beings. To complicate things even more, there is a 3rd person also present who remains shapeless, and exists only through his/her feelings.
I am clothed in white and feel as if I am laying down. However, the third-person perspective sees me as simply suspended in white space. Until this point I am unaware of the 3rd person. Blood begins to flow from my lower abdomen, and gradually soaks through my clothes.
This is where the dream gets the most complex: I feel the presence of a "3rd" person in the dream, and I am aware that they are horrified, and their response to the blood both confuses me and makes me concerned for them. From a first-person perspective I know ahead of time that I am going to bleed, and so the blood does not shock me. The only sensation I feel is warmth (presumably from the blood) over my lower abdomen. I feel completely relaxed. From a third-person perspective I am concerned and confused by the blood, and begin searching the body (which I can identify as my own) for any lacerations. I first evaluate my bare thighs, then my clothed hips, and lastly, the clothed center of my pelvic/lower abdomen region. There I find a dark circle of blood, which I decide must be a puncture wound. Then I - from both 3rd and 1st person perspectives at the same time - open my mouth to speak, and I wake up.
