The term "portal", is reminiscent of the science fiction genre. Here one can use a portal to cross great distances or cross a time barrier.
However, "portal" is also widely used in the paranormal world.

"Portal" describes a kind of gate or door where, for example, energy can pass through. Such portal is said to be able to cross different dimensions or times.

A portal is often said to be found, where extreme paranormal activity is, for example; electromagnetic fields that can not be attributed to electrical wires or pipes. Portals can not be seen or felt, and they can appear and disappear.

La Puerta de Hayu Marka – since ancient times locals report entities use this stone portal. The area is well known for UFO activity and sighting of strange entities.
