Portals (Sandman)

Portals are interactive objects in Sandman. They appear in each level, and have two variations.

Light Portals
Light Portals are the Portals seen at the start and end of levels in Sandman. A Portal consists of a multiocloured energy surrounded by a wooden frame. At the start of each level, Sleepwalkers are spawned out of it, and once all are spawned, the Portal disappears leaving only the frame. It is also located at the end of the level, and is the main objective of the Sleepwalkers. Light Portals can be blocked from entering by pouring sand over them to the point it cannot be accessed. Nightmares cannot enter Light Portals, nor in any way interact with them.

Dark Portals
Dark Portals are a type of Portal seen rarely in Sandman. Dark Portals have a similar appearance to Light Portals, only having a frame made out of black wood that has curled spikes on the sides. The Portal in it is made up of purple, black, and silver swirls. Dark Portals only purpose in the level is to spawn Nightmares. Only one Dark Portal is located in a level they appear in, and cannot be entered by Nightmares nor Sleepwalkers, and cannot be interacted by any of them.
