Camouflage
There is a hidden barrier, which can’t be seen. You can’t pass through it. Your senses are unreliable and you feel like something is pushing you away, you experience a bit of vertigo. It's camouflaged, hidden in plain sight. The light bends around it making it seem like nothing is there. Everything looks normal but one can’t pass through it. Even beyond the human eye spectrum it can’t be detected. Ultraviolet, infrared and shortwave IR, it doesn’t show anything. What about Radar? Radar sends short pulses of electromagnetic energie radio waves, it waits to detect the reflected radio waves to map this out. It doesn’t show on any of these spectrums. Is it even actually there? It's like a secret world. What could be hidden behind there? Maybe it is like a fantasy world full of gorgeous nature and undocumented new special and plants. A place where one could live in peace away from everyone. Or maybe it’s an alien world or a secret military base. Behind this secret barrier could be anything or maybe nothing at all. One could never know. I have the feeling that I should keep this to myself.
