I Have Strange Childhood Memories

When I was 10 years old, I woke up in the middle of night and saw a strange green light coming from my parents room. But it was impossible. My door was wide open and theirs was shut, it had that jagged glass that you can't see through but the light was shining through and it was so bright that it lit up the entire lounge room that was between our 2 bedrooms. I could only see maybe up to a meter into the lounge room. Strangely, it did not light up my room very much. The entrance was lit up a little bit but the rest was dark. Something that stopped me from being able to see clearly into the next room should have given my room a lot more light than that.
I was sitting up in bed and was going to get up and check it out. Unfortunately... I laid down and went back to sleep :/ That is one of my biggest regrets. I asked my parents about the green light the next day but they said they didn't know anything.
I understand that it might sound like a dream but I have no doubt that I was awake and what I saw was real.
