I searched the forums for something like this but I'm surprised I haven't found anything at all. Dream Materials, materials that don't appear in the real world, impossible states of matter and so on. Does anyone know such strange materials from their dreams? If yes, what are they like?

I got the idea of making a thread about this when I remembered the most significant dream material I encountered so far, and to answer the question above myself I'll describe this material:
Empty Water: Empty Water generally behaves like water and has a similar density, however it's color is sorta gray. And it looks, well empty in a way, something one would probably understand better upon seeing this stuff, no material in the real world could look like this. And hence the name: Empty Water.
However empty water is something pretty dangerous, chemically I'd label it with T++, just barely touching it in any way leads to immediate absolute and unavoidable death. It is a little bit agressive physically but you can put it in any sort of metal container without problem. The thing this stuff is aggressive about is the mind, touching it evaporates your very existence as a lifeform itself. There's obviously no antidote for this.

"When the world ends in strange eons, and when all life -even death- comes to an end, the oceans will be filled with empty water, enough to freeze ones soul by looking at it. And yet there are no corpses in this world, the only ones left are those standing and staring at the oceans, with the same emptieness in their eyes."


Out of one of my 2 dreams containing this stuff I know that a very specific mindset however makes it possible to survive contact with this matter. Something you'd better achieve before touching it of course.







Now the question, do you know any Dream Materials?
