Many years ago (in the 80's, I was a child then), i had a dream (not lucid), a recurrent one that lasted a few years. I had it not everyday, fortunately, but maybe I should have dreamed it about 20 times during five years.

I'm on the street next to my house. At the end of the road, far away, i see a big ball of light. It approaches me. Somehow I know that if i touch it, i die. I rush home and close the door. After a few seconds, the ball comes to the door and begins to force it. On the other side there's me holding for the door not to open. I can see a little light through the keyhole. This was always the dream.
In some dreams the door opens, the ball touches me and i wake up. At the time, i gave this ball the name "Pinha", which is portuguese for "Pine Cone".
I never knew the meaning of this dream, why i started to have it or why i stopped having it. What do you think of this?
Do you also had or have recurring dreams for a long time?
