Little girl wakes up to lights and sees UFO.

This happened in Cherry Valley, California, when my family lived on a farm.  
I was about 3 or 4 years old and sleeping in my bedroom, by myself, when I woke up, I saw bright lights through the north-facing window. 
I got up from the bed and I walked over to the window.  I then saw a round spaceship with multi-color lights.  The lights were flashing and rotating.  The colors were blue, yellow, red and green.
I watched in awe as the lights continued to flash and move and the spaceship rotated.  It was floating above the ground.  I can’t recall hearing any sounds.  I also saw a figure in white—they appeared to be wearing a type of space suit.  The figure came down from the craft on a platform and walked around near the craft.  The suit which the person wore seemed like a bee keeper’s outfit, with a sort of flat mask.  
After a while, I crawled back into bed but I remember having a hard time trying to get back to sleep.
I didn’t mention this to anyone until just recently (2011).  I haven’t been back to that area, but I have had one other UFO experience which happened in northern CA, but I that’ll be reported for another location and year.
Date of event may be approximate, although the witness does not indicate that fact.  PD
