You're not crazy, just experiencing your gift. I have had this happen to me, I work with animals and there is definitely a smell associated with their demise. I've learned to recognize it but not over react, just acknowledge it's there. I have a story about a particularly eerie one. My boyfriend and I went up to Vermont on a mountain biking excursion. We stayed at a lovely inn that had an animal sanctuary on the property. There were a few horses in the fields and I went to visit them one evening. Although they were in separate fields, the alert, healthy looking horse was standing very close to the fence leading to the field that the other horse was in. The other horse was nearby and I could tell immediately that he didn't look well. The alert horse seemed to be keeping a very watchful eye on his old friend. This concerned me, animals do know and the healthy horse seemed to be telling me to help him. At that point the older horse began to sway as if weak and wobbly on his feet, very unusual behavior for a healthy animal. I knew something was wrong. I went to the innkeeper and politely suggested a vet come take a look. I didn't want to overreact but I didn't want to ignore it either, I would never forgive myself if I didn't (patient advocate She said the vet had already been out but gave no real diagnosis and just treated him for pain associated with a colic he may have been experiencing. The next morning I went to check him and he was down. I couldn't help myself and hopped through the fence to see if I could rise him. As I got closer, it hit me, the smell was horrendous. I attempted to get him to stand and he would not, a further sign of a very sick animal. I went back to the inn and told the keeper once again. She called the vet and they talked over the phone about it. When she hung up, we checked him again and he was up. They treated him conservatively (did nothing really) that night. I also noticed while I was in his field that there was uneaten grain in the grass, horses live to eat. We left that night and I took the innkeeper's email address to check up on the old guy. He died on his own the night we left. I just knew in my heart when we left that it wouldn't be long until he passed. I just hope he wasn't in a great deal of pain which I was assuming he was. I'm no Dr. but I can just imagine that he was obstructed and perforated his gut. The smell was so bad it just had to be something like that. So no, you're not crazy...it happens.
