any explanations ??

Well, It may be true. I had a weird experience today. My father passed away 15 days ago from a heart attack. It was a shock I felt never before. He was only 52 and in perfectly ok health. Because I live in USA and family in India, I couldn't even see him for last time. We were very close but in a subtle, non verbal way. I have/ had a regret that I couldn't/didn't express myself to him very clearly and maybe he felt like I kind of think of him as inferior or may be I feel I am very clever or something like that. I still have a regret that I didn't spoke with him very expressively like I do with my mom. That, he was one of the real influences on me and I loved him.
Then, I had a very relaxing evening yesterday I slept with pretty calm nerves. Then, I experienced series of dreams, they were super realistic, I was in my own perspective. There was also death of my dad in the dream, but it was hoax. He came back ! I asked him why did he do that, and he gave some explanation I don't remember. I sat on his shoulders and roamed around, maybe I did that when I was kid. He had an accident 2 years ago, which left him with swollen leg. So,I asked about it and he said now it was recovered. My mom was furious with him in the dream. I said to him that he Must not miss him Blood pressure medication and he said ok, though a bit involuntarily. Then, all my relatives were there to see him again (he kind of came back from dead, or it was a hoax played by him, or some thing like that...)
My uncle said to him,'You just ask for the break, don't take a break like that!' and my other uncle asked to drop me back to airport for my flight to USA. And he said that he got it, he will drop me! It was the thing that he did for me on literally every day, drop me to bus station for school, or for other things. And I was woken up, all sweaty.
Later, I called mom, and explained, and cried a bit (the tears just rolled, and I seldom cry...).
Maybe,it was some maze created by my mind for giving me some closure, giving me chance to meet him again... or maybe it was an alternate reality. Or my dad's soul, communicating me when I was very calm minded.
I have no explanation, but from these experiences, I doubt the need of our existence. Our Hindu Dharma gives very well defined and studied explanations of afterlife, and one of the rituals that I did later denoted that he was satisfied when he passed. (He never knew he died, no pain, no fear..)
We are just puppets here, with unseen strings, and I just hope that wherever his soul is, he transcends to higher spiritual level and be happy.
