I hate it when lucid dreams fade. But usually they were of low lucidity, which makes me feel only a little better about not remembering them.

Besides motivation and alarm setting, I (always) suggest you keep a consistent sleep schedule. I cannot stress how important this is in recall! Once your sleep schedule is consistent, you can experiment to see exactly when your REM periods end, so you can wake yourself up to remember them. Even if not used for calculation purposes, a steady sleep schedule still helps with natural recall. I went from writing a paragraph last week to writing two pages this morning--on just one dream!

Oh, I have the same Simpsons.
