Sometimes something screwed up in my dream and I think it's real. Like something that's even physically impossible like flying. And my emotional reaction is as if it's really happening.
Unrelated but awesome.
@Xan: I do get the "icy vein chill" feeling occasionally (like nervousness or intense suspence), but what I mean by tinge is usually a "spill?" feeling, like I can literally feel/taste some sort of substance released and running through a specified part of my body momentarily. It's very very similar to the icy feeling though. Maybe the same thing but feels more like.. a "flavor" than a temperature.
