My first remembered dream

I was about 5 when I dreamed this.  I remember it vividly.  I had watched The Blob on TV.  It is the only dream I remember that was in black and white.   I was riding on top of the Blob while it was flowing up and down stairs seeking out and engulfing people.  I was not afraid.  I think I considered it a friend.  Of course, when you consider my imaginary friends, a black cat, a black emaciated horse, and a devil, it could very well have been my friend.
