Dreams 12.14.14

Was some sort of lab tech again; I was helping set up for experiements, except I was one of those experiments--!  Well, actually, I was being operated on but in order for me to donate something, maybe blood. I set up the area where some physician type was going to do the procedure (in which I would be unconscious), but I then messed up one of the needles (wasn't sterile anymore).  I went to look for a replacement, but could find none - the little storage drawers' contents belonged to other researchers; I couldn't poach from their supplies in good conscience.  By the time I returned to the operating table, empty-handed...everyone else had left.  I dithered, bemused and discomforted.
