Scary facts

Cell

I moved into a new house. A beautiful house, but old, creaky and creepy, but at that price I couldn't pass it up. I was going to fix it up good starting tomorrow
That night, at around 2am, I woke up and went into the kitchen to get some water. I heard some light tapping coming from the underneath the kitchen floor. I recognized that it was Morse. I went and got my phone and opened a Morse translator app. It was simple what the tapping was.
I know a little about Morse code. I don't know it too well but I'm familiar with it as in if I hear tapping or clicking sounds in a certain pattern, I'd recognize that it's Morse. Of course, then I would need to translate it because I don't know it by heart.
Morse app translated the tapping.
"Help"
Over and over.
I opened my recording app started to record the tapping.
"Please help"
I replied back in Morse code "where are you?"
"Cell"
I wasn't aware of having a cellar in this house. I figured it was something the previous landlord hadn't told me about or forgotten to mention it. I had no idea how to get down there. There was a man in my house and I had no idea how to get to him.
I called the police. I was on hold while they were transferring me to the correct department for this issue. While on hold, I replayed the tapping message.
A chill went up my spine.
After replaying the Morse code on my phone...
I had made a mistake in the translation. Due to the raindrops hitting against my window earlier, making a tapping sound as well, I had mistaken Morse code for "C". It was actually "H".
