[lnl911]

I had a dream a few months ago about being in a chair that looked to me like a dentist chair. Well any way i was smiling and their was a man sitting next to me and beside him was a bottle, a large one like the water bottle you fill at the stores or save coins in and i turned to ask him what are you doing with that its so big. The man said well how else can i get the hemoglobien. When I woke up I had to look that word up i knew it was blood but what was it s difinition.
