haunted idea 2

In this idea, I had an idea of shadows, and how they only come out at night, the scariest time of day. Where the shadows will be moving, seem as though you are being followed without no object there, giving a haunted feeling. As hand brushes against shadow, its a portal. peep through it and get curious whats inside, so goes inside portal to a world where there a spikey creatures that are running after you, but seeing a slightly hidden hole, peep inside and looks colourful and safe, hop inside and is more safe than the spikey creatures, as the hole seals itself as they get inside, where the treasure is.
Then the next portal is where the treasure stood, and as you look it is the place where they first came from, the room of shadows, and go through, but as you land, it is day again and all the ghostly and scary aspects are there no longer.
Entrance is a night begins to settle in, with shadows and ghost-like aspects. then exits and leads to a intimidating world where the creatures are spikey and the walls are rugged and about to fall, then exits that world and enters a hidden world with the treasure, which then returns to the beginning world, but where all shadows and haunted aspects are gone as daylight breaks.
