There is a deeper meaning to the Rune Isa. Though the water may appear frozen there is still, oftern, motion below. (even the polar caps nave moving water beneath them.) This can relate to the subcouncious.
It could be that you have reached a point in your life where you need to stop and take stock, maybe you have faced a lot of challenged and changes over the past few years and the fates are saying 'hold fire', for a while. This is not always a bad thing and remember ice oftern thaws in the spring.
