First Memory...What Does it Mean?

Since I can never remember any dream I've had past an hour after I awake, I chose to share my first memory. Though brief, this memory is quite vivid and I can see it even now in my head as I describe it.....

I am maybe three years old, and we (my father, mother, sister, and I) are living at our first house in Missoula, Montana. I have just woken up, and I am standing at the top of blue, carpeted stairs. I can hear voices below, it sounds like my father and mother discussing something. I want to know what they are saying, so I try to listen for awhile at the top of those stairs. Finally, unable to make out anything, I walk down the stairs. And that's it.

For some reason, I remember feeling very alone and scared during this memory. Perhaps I had just had a nightmare? I have no idea what this dreams mean, or is there supposed to be a meaning? Does there have to be a meaning for everything? Maybe I'll find out in this class.
