Were Ты perphaps listening to thriller или maybe had it on your mind before bed? I do that sometimes. We sometimes think about something so much we dream it. I do like your dream though. Sweet dreams indeed!!!!
It seems like he was sad and lonely because Ты wouldn't let him go~ I think he really was cheering Ты up and goofing off with Ты until he made Ты smile. He only went with God after he felt Ты were willing to let him go and be ok with him not being on this earth anymore. That's just my interpretation.
