Odd dream?

I had a dream when I was young that still hasn’t left me, it’s like a ghost. I saw a similar image to this one [https://pin.it/60mqFpWIk], but I was in a car, riding in the backseat. Out the car window I saw tall white figures. They didn’t mean me harm, in fact, they adored me. They didn’t tell me that, I just knew. They didn’t have faces, but they smiled. In retrospect, they remind me of the cows I grew up around. What does this mean? Was it a warning? Did the actually adore me? Did I fall into another universe? Was it just a weird dream?
