An added existential horror comes from the fact that Scenarios 1, 2 and possibly 3, also describe what is going on with in vivo human consciousness housed in a brain.
The upload scenario can be said to be just a gimmick to bare the philosophical problem, we already are simulated on computers, just ones made of fat and protein. Its simply more socially polite to consider this ideas when talking about Uploads, since we do not have any, so it is a little less freaky to think about. But this does not change the fact that even participating in this discussion forces us to experience Scenario 1 with bits of Scenario 2 necessary to maintain continuity, and if any one of us falls asleep, they will unwittingly participate in Scenario 3 as well.
