The paranormal is defined as the place where life and death are said to meet in the middle, the place where life and death are said to exist together at the same time. However, some of the instances like hauntings are said to be images of the past. Despite having those types of events harmonizing assumptions with the present time flow and intergalactic medium, nothing changes the fact that they are still events that have occurred in the past.
What usually happens is that the ghost will loop through this time plate which will then create an event that had happened in its life over and over again like a movie clip on repeat. This is possible because we each have a soul which is a ball of energy. This lives inside us and causes the movement of life without any strings or batteries. Being an energy source, it has to get rid of bad energy for it to be able to produce new energy. The said disposal of energy causes a ripple in the time plate of the said moment and happens up to 60,000 times in a minute or 1000 dumps in a second. This results to a memory loop in the paranormal and termed as impressions by emphatic psychics.
There are beliefs that time travel is not possible but when similar technique is impressed into the time plate that will take you back to a certain moment in time, a person could see herself/himself doing the things that s/he did in the past including the recent ones.
Ghosts walking through the walls are caused by the time plate coming to the surface which is closer to the normal presence of an event which had happened in the said location with the door and window moved or the building had been remodeled recently. Then, when a ghost walks through the wall, it is possible that a door had been in existence in that very location. Those instances wherein ghosts are seen coming into a room and saying something unintelligible is also caused by the same looping chaos change of the time plates.
