So recently I decided to begin writing my own SCP, and I would like to not only know what potential future readers feel about the concept, or if anything like it has been done before. I don't want to end up making a imposter of another SCP.
The concept of my SCP is this: a cassette player that when activated produces a song that forces all who hear it into a state of exhaustion to the point where they immediately seek sleep. Once asleep, the individual will seem to awake in the same exact location, just not truly. Technically they are in a shadow dimension where everything in the real world is still occurring, however the individual in unable to be seen by anyone except the entity residing within this shadow dimension. After prolonged exposure to this SCP, the entity residing within will begin to manifest in real life.
Thoughts on the basic concept?
