 The  innumerable recorded cases of past life experiences are proof of the   concept of life after death. In all the recorded cases of rebirth, it   was found that there was a variable time lag between the death of the   person and his next birth on Earth. So, where does the person go after   his death till his rebirth on Earth? Is it a single place or are there a   variety of places? If so, what are the factors that decide where a   particular person will go to after death?

The places a person may go after death
  
When  a person dies the physical body ceases to exist. However, the  rest of  his existence or consciousness continues. The person minus the  physical  body is known as the subtle body and it comprises of the  mental,  causal (intellect) and supracausal bodies (subtle ego). 
  
The various planes of existence
  
There  are 14 main planes of existence in the Universe. Seven of them  are  positive planes and seven are negative planes. The seven negative   regions are commonly known as Hell. There are numerous sub-planes within   these main planes of existence.
  
The human subtle body after death goes to one of the 13 planes of existence other than the Earth plane.

One of the best True Experience I have ever read about this topic is below:
Written by Janis Amatuzio, M.D.
In the winter  of 1994, police officers discovered the tracks of a car  leading off the  roadway, overturned into a frozen creek bed. It was  4:45 a.m., the  engine was running and the driver was slumped over the  wheel with  obvious head injuries. Paramedics rushed to the scene and  transported  the victim, later identified as a 26-year-old man, to the  ER.
Extensive  head injuries were diagnosed, and despite all resuscitative  efforts,  the young man was declared brain dead several hours later.  After  confirming positive ID, his wife was notified.
As  county coroner, I was acutely aware of my role in approving the   donation of organs without compromising the death investigation process.   The patient met the criteria for brain death, but since the death was   due to trauma, a coroner's investigation was indicated. 
I  spoke with the attending surgeon and he told me the family would  like  to donate his organs. "I'll allow donation as long as it doesn't  impede  my documentation of injuries and determining the cause and manner  of  death. Do you see any evidence of injury to the chest or abdomen?" I   asked.
The  attending surgeon responded, "It appears to be all head injury.  The  chest and abdominal scans read as clear with no evidence for  internal  injury." 
"OK, thanks. I'll approve the organ donation before the postmortem exam."
I  finished my hospital duties that afternoon and hurried through the   underground tunnel to get to my desk in the coroner's office. From a   distance, walking toward me, I saw the hospital chaplain. He looked   concerned. As his eyes met mine he stated, "I have to talk with you   about the fatality in the emergency room." 
I  stepped up my pace to meet him in the empty tunnel, responding, "I   spoke with the attending physician and OK'd the tissue and organ   donation prior to the autopsy."
"That's not what I wanted to talk with you about."
As I unlocked my office door, he asked, "Do you know how the body of this young man was found?"
"Yes," I said, "by the Coon Rapids Police Department in a frozen creek bed at about 4:45 a.m."
"No,"  he said. "Do you know how they really found him? I spoke with  his  wife. They were recently married. When I was talking with her she  said  something that really stopped me." 
He  paused and held my eyes with his. "She told me that at about 4:20  a.m.  she had a dream, a profound dream, in which her husband was  standing  by her bedside apologizing, telling her that he loved her, and  that he  had been in an accident. His vehicle was in a ditch where it  couldn't  be seen from the road. She abruptly awoke, called the Coon  Rapids  Police and with absolute certainty told them her husband was in  an  accident not far from their home and that his car was in a ravine  where  he could not be seen from the road. His body was discovered by   officers less than 20 minutes later."
I  felt a chill go down my back. "Let me call the PD," I said as I   reached for the phone. The desk sergeant on duty confirmed with his   dispatch the time of her call and content. "Amazing!" I said to the   chaplain. "Did she say anything else?"
"Yes. She told me that it didn't really seem to be a dream - he was really standing there, next to her bed."
Later,  I pondered my conversation with the chaplain and reflected on  my  caveats to death investigators: gather information, document the  scene,  follow the guidelines and observe and trust that you will arrive  at  the truth. 
Standing  at the crossroads of life and death, I occasionally catch a  glimpse of  a greater mystery and a larger truth. There was no doubt in  my heart  that our conversation shared that late afternoon in my office  felt  true. But there was no way to prove it to a reasonable degree of   medical certainty. It was simply there and seemed more of a reminder   than a challenge. It lifted my heart, and I began to understand a little   bit more about what really happens.
Amazing isn't it??
