Long lost friend

Where did you go my friend?
I have been searching for you for the last couple of years and I can not find you anywhere?
You used to come to me in the night and stay for hours.
We would travel to exotic places together, just you and me.
Remember the time we were on a sailboat in the middle of ocean or perhaps you remember when we took a trip to that cave high up in the mountains. No?
I have so many fond memories with you. You have taken me to places no one else has, and no one else ever will.
Sometimes I feel you are near but just like a whisper in the wind you are gone.
I wish you would return to me, my friend. I miss our long uninterrupted nights alone, together.
My body would just relax and you would take over.
Hours upon hours we would spend together in bed.
Why do you elude me so?
Please return to me.
I miss you, my friend, Sleep.
