Are dreams just that?

So I've got Jon a little upset with me (in a joking way) because the last two nights I have had clearer dreams than I've had in like forever. So the first night, I had a dream that Jon was called as a general authority, but all of our kids were all grown up. I didn't tell him this part, but part of it, my dad was also called as a general authority with him. My dad part could be likely. And then the next night I had a dream that we had another baby, it was a girl, and she looked exactly like Kaylee and Abbie combined. I told Jon it was a sign, he didn't like that. He is not ready for another one yet, and actually I don't think I want another one quite yet... maybe in about a year or so. But that dream got me really thinking... are dreams just dreams, or could it be a way of telling you something you are supposed to hear and that is the only way to get through to you... obviously not about the general authority thing, but the baby thing... its got me thinking and confused. I mean I saw this baby clearer than day, all of her features... it was pretty cool.
