Scary and recurring dreams

These aren't recent dreams, but they are nightmares I have had in the past as a child.

The background was white. Everything looked like a white screen. Suddenly a little, black arrow that represented something would zoom across the "screen". It would scare me alot. Suddenly, I could see a rocket launching. I was horrified at this point, dreading it.

That dream I have had several times, young and old. I always wake up horrified.

Another one is that there are 3 babies. They all have frilly hats on and rattles, and they get closer, giggling and rattling. For some reason it was always scary. I only had it 2 or 3 times when I was younger.

The last once wasn't scary, but I remember having the dream a few times.

I was on a farm with my school friends. One that stuck out was a kid that seemed to have mental problems. They all worked with me, and we looked after chickens
