This may sound a bit mental but I am anxious at the moment anyway and this has got me worried. Last week I kept seeing a black cat sitting in my garden. I said to myself if that cat is still there later I am going to die (I am a bit weird about death and get very anxious about it). It was still there an hour later. It was there again the next day then the day after I saw it crossing the road outside my house late at night. Not seen it since.
Today I was going to the GP and next to the cornfield was a crow looking straight at me. When I came out it was in the field and looked at me again.
Freaking out about it 
I know I sound mental sorry.
