I kind of believe it because there will be some moments when I will be thinking about a family member who is dead and I will be thinking about them and then something good will happen to me

When I was a kid, I woke up in the middle of the night because of a bad dream I had, I went and banged at my moms door to wake her up because I couldn't go back to sleep and wanted some comfort. As I'm in the hallway banging on my moms door I look over to the left and I see my grandma walking towards me, ( my grandma had just passed away within the past year ) I was frozen for a moment cause I couldn't believe what I was seeing but as I walked towards her she vanished as soon as my moms door opened. It looked as if when she was walking towards me with her arms were spread out as if she was going to give me a hug. I didn't talk about what happened because it didn't feel real to me but I know what I saw and I know i was awake when it happened.
