Need info. Is this the movie where..?

I'm pretty sure it is, but I've been looking for this movie for a while. I saw it a long time ago with my dad (I was a lot younger...probably 7 or 8?) and I always wondered what it was called because I'm obsessed with alien/UFO movies and stuff.

-I remember the family driving in a car...at night maybe? And then I remember them getting abducted or something.

-I remember them sleeping and having nightmares about aliens.

-They had a house with a large open staircase. Guys in black and sunglasses came to their house, followed them, taunted them, etc.

-At one point one of the men has his sunglasses taken off and he has black eyes like an alien or something?

-Eventually the family moves into a new house, and then you see one of the black cars parked outside. I think that was the end.

Like I said I think this is that movie, but I just want to be sure. Thanks.
