I went to Starbucks this evening to hang out and write for a bit. When I left, everything in the house was fine and dandy; I had a good time out.
When I got back to my house, I was completely unsuspecting of anything going strange. I walked up the front door whistling, took out my keys, and unlocked the screen door. We have a deadbolt as well as a doorknob lock on our front door, so I unlocked the deadbolt first. I stuck my key into the doorknob lock and turned, and just as I unlocked it, the door whipped open, fast. The keys were still stuck in the knob as it whipped open and hit the wall inside of the house. I just froze, wondering if somehow some kind of wind draft could have done that. It was such a sharp jerk I thought for sure that my mom (who was sleeping at the time this happened) had pulled it open quickly for me from inside. All I know is that somebody opened the door, no matter how many don't believe me.
I have had experiences in the same house on the date of my grandmother's death (I reside in her old bedroom) such as things moving and thuds on the wall after I make comments aloud like, "Wow, creepy, I've got to be imagining things." Things have moved around me before, and in fact, the same set of keys I mentioned earlier have fallen on the floor before.
Even though I get horrified at these things when they happen, I'm mostly just getting shocked that they are actually happening to me. I don't actually get a bad vibe or anything; I don't know if it's my grandmother trying to help me out, or if it is something else.
I just thought I would post and see if it was normal for things like this to happen at random times, and if there is any reason a ghost would help out with opening doors for you!
