dexter,
Thank you, I appreciate your fair post. I think the phenomena you're talking about do exist, but I don't really see them as likely candidate explanations for the behavior in this instance. It is true that sports fans, e.g., often see what they want to see. It is true that people cling to comforting beliefs, even about experiences, despite the improbability of those beliefs being true (although, to take the toast example, and many of the other religious examples: the thing they're probably wrong about there is the interpretation, not the experience. It's just not so unlikely that toast burn might look like a face if you squint just right).
On the other hand, we're talking about claimed multiple meetings with somebody who had died, one of them putting his hand in His side, a miracle (the fish), etc. Let's say that, at the least, they would have to be well above average at self-delusion, which I think is putting it really mildly.
Perhaps the closest to something like what you are saying might be Paul's experience, except that he did not want it, and in fact was opposed to the Christian message.
As for the rest, I think there are few signs that they were expecting a resurrection. Philip had the opposite reaction from what you suggest, e.g.
So anyway, I don't really find your suggested explanations that convincing as analogies, or believe that they can explain the facts of the early Christian movement. However, I appreciate the post.
