So my story starts two days ago. I received a call from my sister that our grandmother had passed away in Florida; I was never really close to her and was shocked but not upset. I went to bed at around 12:40 with my iPod and listened to two songs. I felt myself about to fall asleep so I turned it off rolled over and fell asleep. Suddenly my body jolted up, like when you dream you're falling and you flinch and wake up. But I didn't have a dream of falling I just FLINCHED HARD! I opened my eyes and saw a woman in front of my closet reaching at me and coming closer, I froze because I thought I was being robbed. But she suddenly vanished and once I realized what I saw I called my friend and talked to her about it. I woke up hot and sweaty which is weird because the room was cold and I was in a ginny tee and sweatpants which I always wear.
The next night I have a dream that the ghost is contacting me through my AIM account and its typing to me in a symbol code and I have translations written on paper. I type back to it to leave me alone and it says it won't. I tell it no you have to, and it typed back "./././" before I could see the translation my phone rang and I woke up.
Is it my grandmother saying goodbye and if so why would she say things to me in code?
