This happened when I was about 8 or 9 years old, I was sleeping on the couch in my living room. It was about 9 or 10 o'clock and I was having trouble sleeping, so I turned on my television and watched TV for about an hour. As my favorite show was about to end, two figures appeared in front of the TV, I looked up to see the faces, and they were of my great grandmother and great grandfather. They said something I couldn't hear what, then they said (And this was about a week or two after my great grandmothers passing) "Brooklyn, we are together now, just let your mom and granma know we miss you all" Note: My grandmother said that, sorry I forgot to mention that before. Then my grandfather said "We miss you, please remember that." This sort of startled me, especially being only 8 years old. I closed my eyes and re opened them about 20 seconds later, they were gone. So I covered my eyes and started crying, my granma came out and asked what was wrong, I told her the story, and we both sat and cried for a while.
Then we both fell asleep on the couch together. We told my granpa the next morning (He is not a believer in the supernatural) so we got sort of mad that he didn't believe us. I must add one more thing before I end this, I forgot to mention my granma had the same experience at the same time I did.
I'm not sure if it was my imagination, would you guys know?
