My values seem to be pinned on these ideas (the ones that are not true) because while I am in the process of caring about the things I care about, and especially when I am making a choice about something, I find that I am always making the assumption that these ideas are true -- that the states of the universe matter and that I exist forever.

When it occurs to me to remember that these assumptions are not true, I feel a great deal of cognitive dissonance. However, the cognitive dissonance has no resolution. I think about it for a little while, go about my business, and discover some time later I forgot again.

I don't know if a specific example will help or not. I am driving home, in traffic, and brain is happily buzzing with thoughts. I am thinking about all the people in cars around me and how I'm part of a huge social network and whether the traffic is as efficient as it could be and civilization and how I am going to go home and what I am going to do. And then I remember about death, the snuffing out of my awareness, and something about that just doesn't connect. It's like I can empathize with my own non-existence (hopefully this example is something more than just a moment of psychological disorder) and I feel that my current existence is a mirage. Or rather, the moral weight that I've given it doesn't make sense. That's what the cognitive dissonance feels like.
