SCP Foundation

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?

Crit Inbound! ETA: ~24 hours!

I remember seeing something like this in a tale from the "On Mount Golgotha" canon. One of the tales had a bunch of people get knocked out by a memetic cassette that put everybody to sleep. This let somebody steal SCP-012, which the entire canon is built around. I normally would suggest talking to the authors in that canon, but as far as I know, OMG hasn't been active in like 2ish years. Regardless, maybe you should talk to psul. They may just want to revamp the canon, after all. A little idea workshopping with them and the other writers of OMG (WrongJohnSilver and Decibelles, primarily) might be able to steer this in a really cool direction.

As such, I recommend you read the On Mount Golgotha canon. It isn't super long and it adds some much needed content to SCP-012. I finished it in a couple hours of reading, if I remember correctly.

It is also worth mentioning that I don't care for the cliché monster at the end at all. We already have so many trans-dimensional/extra-universal monsters that adding another one to the heap may just drag your article down and artificially inflate the danger. I suggest taking the idea in a different direction to avoid these clichés, if at all possible (hence the OMG idea).
