Audible noises similar to humming or low-key buzzing sounds may be heard as a portal opens or closes.They may sound far away but could be very near.Any odd or unusual sensations could also indicate the nearness of a dimensional portal.there may be static electricity in the area around a portal.there may also be transference of energies whether it be etheric or from higher frequencies,that could cause communication with otherworldly beings.

You may be witness to physical objects appearing near you on the ground.These items did not go unnoticed by you-they were not there before.Crystals,arrowheads,stones,feathers,jewelry even masks and many other apports( solid objects beleived to be teleported from another dimension)have suddenly been discovered lying near portals,although nothing was seen at the time.Any form of matter that is synonymous with both dimensions is able to interconnect and teleport between the two dimensions.
