If it’s a sliding sound, like someone dragging their foot,....RUN!!!!............
“Appypappy, I was on a archaeology trek to a pyramid when we found a Sarcophagus. We opened it and we found this book. I took the book. Let me read to you something from i....where did he go?”
My kid brother did that in/1950 and we beat his ass from 18th to 22nd street in NYC on the way home.
My sister and I busted our chops and cobbled 60c together for the movies (20c for kids in those days). The Mummy was playing so we all went down to get scared. Midway through the movie, the mummy comes up a gravel driveway and my brother lets out a blood-curdling yell and runs out. We followed and stopped him but the usher wouldn't let us back in without ticket, hence the opening statement.
We hassled him about that for years afterward. He said he was OK until he heard the mummy's foot dragging across the gravel and the sound freaked him out.
It wasn't until a late night rerun in the '60s that I was able to see the whole thing through.
