1 Tooth-Faerie – Done as a sacrifice to honor the Alfar & Frey, there king, in thanks for the growth of the kids teeth to come.
2 Christmas-Tree – Actually a Yule practice to represent Yggdrasil. The ornaments are sacrifices made to the gods. Probably (maybe; just a theory) also given to appease Odin and the wild hunt. Notice how many ornaments are human like? Maybe this was so the wild hunt would take these symbolic people instead of real people.
3 Wishing-Well (Fountain) – Is a magickal practice used to place something into the 3 sacred wells (Hvergelmir, Wyrd, Mimir) so that it may manifest into ones Wyrd. Like as an example. If one wanted a car they could toss a matchbox car into a body of water while wishing for a new car and picturing what kind of car they want (and the tiny toy car should be one that reflects this model).
4 Piggy-Bank – Represents Frey’s golden Boar. Frey is the god of fertility and abundance (which is associated with money in modern times).
5 Drinking-Toasts – This is merely the modern survival of the sumbel ritual.
