Why the ending of LOST makes no sense

The more I think about the ending, the less sense it makes.

That is not a good sign.

Here’s what I don’t understand:

According to Christian Shepherd, “This is the place that you all made together, so that you could find one another.”

But when the dead LOST-ies made “this place,” why did they construct it in such a way that it blocked their own awareness that they were dead? Why did they create a convincing alt-world for themselves where they all had new lives, with no awareness of their past? Didn’t they come to “this place” specifically to acknowledge and let go of that past?

They were the ones who created “this place.” They could have made it anything they wanted. So why did they make it a place that blocked their own memories, when the reason they were there was to process those memories?

Why did it take Desmond to wake them up so they could begin to remember? As matter of fact, why did Desmond even want to wake them up? What was it to him?

Even more puzzling, since they were all initially unaware that they were dead, and thus unaware that they were creating “this place” out of their imaginations, then how did they all synchronize their imaginations to create the SAME place for all of them? Did they attend some sort of Second Life workshop right after dying and before heading out to the alt world, where they hammered out their new world before stepping into it?

It just doesn’t make sense.

I could go on. And I will. But the vastness of the things that don’t make sense is overwhelming, and I must retreat to an alternate reality for a moment. 😉
