Speculation Without Spoilers

[Mod-Tigerkatze]

Please use this thread to speculate about the show as well as the ghosts and their abilities (or lack thereof) without spoilers. 

If comparisons to the UK ghosts are drawn, kindly take a moment before posting and consider if the information you reveal can be seen as a spoiler or not. When unsure, please be so kind and be safe rather than sorry and spoiler-tag. 

Thank you and happy speculation!

There's a wide variety of beliefs about afterlife, quite a few included in the Wikipedia article on Afterlife. The Sufi belief seems different than many; it could be interesting if Sam encounters a Sufi ghost:

Quote

The Sufi Muslim scholar Ibn 'Arabi defined Barzakh as the intermediate realm or "isthmus". It is between the world of corporeal bodies and the world of spirits, and is a means of contact between the two worlds. Without it, there would be no contact between the two and both would cease to exist. He described it as simple and luminous, like the world of spirits, but also able to take on many different forms just like the world of corporeal bodies can. In broader terms Barzakh, "is anything that separates two things". It has been called the dream world in which the dreamer is in both life and death.[89]
