I think He does, but i also think that the large majority of Christians who think it has happened to them are wrong. People assume that because a dream is spiritual in nature, or just has a lingering effect it must be from God. It doesn't matter that it is never confirmed to be from God. Personally, if i were you, i'd just pray about it, keep it to yourself and don't focus on it. If its from God just pray God will confirm it. But otherwise i wouldn't jump to conclusions. Or make an issue out of it.
I've had plenty of dreams that lingered. I've had friends who have had the affects of dreams stick with them for days that ended up nothing. Dreams are when we process events and thoughts in our lives. Sometimes those may have powerful feelings that are brought out in us, and those feelings may stick with us a while. So be careful when you apply something as being 'from God' that can't be easily confirmed as such.
And on a side note, you will want to pick a bigger font, or a stronger color. The font is too small for the lightness of the color and makes it a bit hard to read.
