Hi Rod. Anytime you dream of water, pay very close attention to it's make-up and color. Each aspect of the water in your dream represents your waking life or something soon to come in your waking life. (You will make the ultimate final decision as to whether this is representing your current life situation or if it has not yet come to pass)
Your dream does not have the greatest Foretell behind it but all in all; everything will turn out fine.
For the water to be dark, large waves and rough waters symbolizes and fortells of some sort of uphieval. This may be emotional, financial, ect. (For me, it usually comes to pass within a maximum of a weeks time) Your home withstanding this water and your feeling of safety is a sign that you can handle whatever is surrounding you at the moment or handle whatever is to come. It is to inform you that you have the strength to overcome whatever comes at you. I have learned that the water dreams are not specific as to the magnitude of the situation though. I can have a water dream and 4 days later have something happen that draws me to tears and within 1 day, i've pulled my way through or the opposite will occur and it will be something of greater scale.
To dream of clear blue water, stilled water is to fortell peace and a period of genuine happiness. It foretells good fortune as I've always found this to be true as well.
You could take this dream another direction and state it was something of the future but I have a hard time decifering when my dreams are futuristic or not until the event actually occures and I have an "Ah ha" moment so I wouldn't be the best one to disect your dream in this manner. I would say this is NOT a futuristic dream though only because you state the type house you were in would NOT have withstood the storm in a true life situation.
In additon to what I read into your dream; here are some added points. add them in as you see fit. 
Ice
To see ice in your dream, suggests that you are lacking a flow of ideas and thoughts. You are not seeing in progress in your life. Alternatively, you may be feeling emotionally paralyzed or rigid. You need to let your feelings be known.
To dream that you are walking on ice, indicates that you are standing on shaky or instable ground. You are taking risks that you shouldn't be taking. Fear and caution are also implied.
To dream that you fall through ice, suggests that your emotions are threatening to come crashing through.
-- If I were you, I would not fret, just simply realize that a hard time may be coming, ask God for guidance through it and know that all will be fine. For all you know, this dream is only foretelling something quite small that upheaves you for a couple hours, only to emerge peacefully again. Good luck dear.
