Just to make it clear I am super hypochondriac.
I have self diagnosed myself with cancer ,heart problems and whatnot .

Now a few days back I woke up in the middle of the night and I thought my dog was breathing heavily besides me but he wasn't there but I could hear my dad snoring from the other room .but it felt very real that my dog was breathing just besides me(I slept very anxious that night).
Next morning I started fearing I have schizophrenia.

Now In hindsight couple of weeks back I thought a couple of pro golfers whispered among themselves that I shouldnt be playing here(I am highly self conscious,so much so I was expecting them so say it).but now I think no one would say such a thing and I was hallucinating.
I also thought I saw a glimpse of a couple dogs at the golf course(not even a glimpse)but they weren't there when I looked again.
Yesterday I was out with friends and I thought one of the friends had a mean smile for a couple of seconds while I was drinking(but I no he would never do it).
Should I be concerned?
