or shadowy figures are fourth dimensional astral bodies, the stream of consciousness or life force without a human container. The ghost’s ratio of dark to light energy will show up in how dark or light gray it appears. They generally carry the same amount of light they had at the time of their container’s physical death. Ghosts are only found in the dark bandwidth. Ghosts are frequently spiritually confused and it is generally helpful to them if you can share what you know and open a portal of greater light for them to enter.
Those residing in the light bandwidth wouldn’t show up as a ghost. Light entities are aligned with quanta truths, the quantum field and compassionate thinking. Their rapid quantum spin or consciousness enables them to easily take any form for as long or short as they wish. But their unique personal signature frequency or vibration will stay the same. They change form to put humans at ease. They would include our soul conglomerate, Celestial and Galactic family members, aliens or extraterrestrials and many others.
