Spirits Make You Fall Sick?

My granddad was admitted to hospital to get stitches, because he fell down. He's been kept there for observation, since he is quite old, so we went to visit him recently.

The first day I went I felt horribly fidgety and nervous, the minute I entered the hospital. I saw something of the last patient who was in his room, who had a stomach problem, I think a tumor, because I saw the operation, we're they opened his stomach. The operation failed, and he was given intense medical treatment, but died in the end. I felt cold and horrible. Luckily, my granddad needed to sleep, so we left the hospital.

The second visit, we sat outside his room. It was worse outside. I felt anxious and needed to run away. My mom actually had to take me for a walk. I could see things, but not exactly. It was like my vision was almost distorted, after images lasting longer than they should, light seemed brighter than it should have, I felt very uncomfortable. We stayed for a good 2 hours, and I had to be "walked" about three times. I concentrated simply on the patterns on the tiles to keep my mind off anything else, but I kept feeling like there were things near me, like something was sitting next to me, or on top of me, or maybe even bellow me on that bench. I got strange chills all of a sudden, on a single bit of my arm, and suddenly a strange furry feeling, like a dog was wagging it's tale on my feet.

I couldn't see it, but I could feel a rocking chair...I'm not sure how to explain it, there was no rocking chair in that corridor, but it's like one ought to have been there. By the end of it, I felt awful, mainly because I wasn't good company for my granddad, and because I felt almost queasy in that hospital, and I wanted to run out.

The minute we were told to leave, I ran down the stairs and out.

I should possibly mention that in my granddads ward, was on the first floor there are three people. They are about seven rooms apart from each other. I don't think I contracted anything from them, but the minute I went home, my throat went horribly soar, and I contracted a raging fever. I'm the hardiest of my entire family, and none of them were sick, not even my mom, who "walked" me, and who gets sick very easily. My sister had been sick, but it was food poisoning, and she had no fever. So, is it possible that the hospital made me sick? Or is it just one of those things? What's going on in that hospital; am I weird or is there something else? I have to go again...so...what do I do?
