Can someone interpret this?

1. I was in a dessert, I saw my dad riding a motorbike/ATV, he looked like a insane man with a loopy face and laughing uncontrollably (happened in 2013)

2. I was with my mom in a music store, I saw my dad looking at CDs, I realized it was a dream because I know he already died, I stared at him but he was like a total stranger, I didn't approach or talk to him either (happened later in 2013)

3. My grandma came to my house, she was angry, she told me about a family event that was being held, I went to the mentioned place to checked it out and turned out to be a lie (happened later in 2013)

4. I was burned in hell (happened in 2014)

5. I was in a dark alley going somewhere and there was someone stalking me in the shadow, I feel threatened and ran (recently)

Sorry for having so many dreams, these dreams are the only one that I remember vividly until now. I really want to know the meaning of these dreams, I always woke up crying everytime I had a dream.

P. S. My dad died in 2010 and my grandma in 2012. I don't have much moments with my dad because my parents were divorced since I was 1 y'o. I'm really close with my grandma and considered as her favourite grandchild by my cousins

The dreams posted, are mostly your mind processing and dealing with the death of your father and grandmother. Feeling threatened may have some thing to do with a situation in real life where you feel threatened.
