I vision a different situation here. I think the smile on the eraser indicates it has escaped from a torturous environment and doesn't care that its fate may be to be run over. Or, scenario #2: It smiles because it knows a kind person like you is going to find it a happy home to rub away in to its heart's content. Just keep feeding it the odd scribble here and there and it should grow to be a fine outstanding example of its kind (or disappear trying!).
If you aren't seeing Heaven while you dream, you're doing something wrong.
Dreams allow escape from the passage of Time.
The ultimate activity is the Dream.
