The vikings and the northern lights

In the old times, there was a lot of superstition going on behind
the northern lights. Lots of stories have been told to kids
throughout history, but my favorite one is the ancient viking tale:
When vikings saw a northern light, they would not be scared, they
would actually feel proud.
A northern light, according to the old norse culture, was the
reflection of the sun on te shields of the walkyries, which were
coming towards the earth to take the souls of the bravest
soldiers who had died in a battle. A red northern light would
mean a bloody battle.
However, this was not a bad omen: first of all, dying in a battle
was the proper way of dying: if a soldier would die of sickness, he
would go to hell. On the other hand, if a man died in a battle, he
would go to Valhalla (heaven), where they would live a non-stop
feast eating the flesh of Særíhmi, a giant pig that would never
run out of meat and drink from a drinking horn
tat never runs out of wine. This feast had an ending point: all
these souls were commited to protect their gods when the
Rágnarók would come: the moment when the giants would rise
and atack Valhalla.
Therefore, northern lights were considered a good omen, since it
meant that Valhalla would have more protectors.
There are of course plenty of other myths about northern lights:
they have been explained as the souls of kids playing on the sky,
or just a sign for lucky kids to be born if they were conceived
under the northern light.
Such an amazing phenomenon, and so many myths...
Do you know any myth?
