what is ectoplasm, really?
And can it be explained by any other phenomena other than ghosts? For the beginner, ectoplasm is the supposed residue left by spirits. This concept became especially famous in the time of Freud, and made up a large portion of the Spiritualist movement in the twentieth century. According to studies done during this movement, ectoplasm can take many forms, but is often seen as a yellow-green hue or ooze around a ghosts body. Ectoplasmic residue is often spotted in pictures, when a ghost interferes with a shot. It can also be spotted in the air and sometimes with a special flashlight or pair of goggles. At times, moving through ectoplasm has been “noted” to be the cause of illness or possession. Breathing or exuding it is a sign of being in contact with the supernatural world.
