Hi everyone. How are you all doing?

Well, I found a strange alley on my street. For three years, I was sure that this alley didn't exist during my commute home from work at night. But one day, while I was coming home from work, I saw this alley, but it went unnoticed by me because I was tired and sleepy. However, I noticed some strange sounds, similar to growls.

The next day, on my way to work, I noticed that the alley wasn't there, which I found strange. On my way back from work, I saw the alley again. I talked to some people and the police about the alley, but everyone said I might be going crazy and that there had never been an alley there. The police said they had gone to the location to investigate, but they said there was nothing there. I had the idea to take a picture to try and prove to people that I wasn't crazy. I took the picture of the alley when I was coming home late at night from work as usual, but for some reason the alley didn't appear in the photo. I tried every way to take a picture of that alley, but I never could. Then I remembered that I had an old camera at home and decided to try taking a picture of the alley with that camera. Incredibly, it actually worked.

The moment I was getting ready to take the picture, suddenly a pair of white eyes and a loud growl appeared in the alley and I got a fright. Because I got a fright, I ended up taking a blurry picture and it came out out of focus.

Do you have any idea what it could be or any idea what I can do about it?

Here is the Polaroid photo of the alley:
