Leon....It may be difficult to help you out, but I'll offer my opinion and hope for the best.
As for Fairy Dust, I'm sorry to be the bearer of bad news but "Tinker Bell" retired many years ago, leaving her Company "Fairy Dust R Us" to her daughters, the Tinkerettes, Sadly, as fate would have it, the Tinkerettes were like their father, Peter Pan & refused to grow up & manage the business responsibly. Alas, they literally "Blew" the Fairy Dust.
If you're desperate, try collecting the dust bunnies around the house. Most people don't know the difference. You may be able to pull it off!
Moon Beams are tougher to gather. Of course you can only capture them after dark and then only when the moon is visible. If you leave your windows free from obstruction, you could be lucky enough to catch a Beam or two. Since they're elusive little buggers, they must be utilized before daybreak. This can be frustrating. In this case, I suggest you down a pint of Jim Beam, pass out and experience some far-out dreams.
Good Luck, Leon!
