Is it normal to see things that aren't there at all?

Okay, let me tell you what happened first.

My sister and I were driving down a country road looking for someone. Actually looking for that person's house, so we could then visit the person. Anyway, we're driving down this long country (basically one lane) road and we pass a few houses, but none of these are the house we're looking for. So, we keep driving and there's nothing for miles. We can't turn around and go back because there's nowhere to turn around. We know the road eventually leads out to another road, but not for a long time. So, I think I see this run down house with a driveway. And I say to my sister, "there's a house. We can use their driveway and turn around." I'm driving pretty slowly because it's old gravel. So I'm keeping an eye on this house and am fixing to turn into the driveway, when all of a sudden the house disappeared. No house, no driveway anymore. I asked my sister, "why did you tell me there was no house there?" and she just thought I actually saw a house, but she never saw it.

Anyway, I was not sleep deprived, or under the influence of drugs or alcohol at that time. So, I was wondering if that was normal to have that sort of experience. Or do I have something wrong with me?
