Thanks for everyone's replies!
I chatted more with dearmissie via pms, and I thank her in public, she is a very sweet and caring person.
Well my biggest stressor these days was my dog's death, and the delay of his cremation. Because he was my first dog, and I was with him 24/7 he was more like a child to us rather than just a pet.
Me and hubby are going through so much pain, but the day before the nightmare we made love for the first time after our dog died, and although it was pleasurable it stirred up feelings like guilt, anger, sadness, loneliness... We talked about it, and we agreed we need more time before we get back on our regular routine and habits. Physically we function just fine, emotionally not just yet...
After talking with dearmissie and thinking of her input I think the blood thing was a symbolism of losing my dog, not feeling pain was about the way I deal with pain in general and also these days (with medication) in order to numb everything.
The warm salty water (tasted like tears) is the hysteria I went through and my need to "purge" all my bad feelings, and cry/mourn for my loss...
