Four years ago my friend died unexpectedly and for a while I sensed a spirit with me and was almost being contacted by him. A couple months after he died I experienced sleep paralysis and lucid dreams involving him and I was in a place very important to him when it happened. I tied these things to him but I wasn't sure. Nothing unusual happened for a while until a few months ago.
I moved into a new house and a couple months after I did, many things started happening. I often felt a hand on my left shoulder when I'm alone, I have a recorded video of a repeated tapping on the window by my bedside and the window is two floors up and facing the street. I didn't think much of anything until tonight. I've been lighting incense a lot in the past couple days and today it started. My closet door that's shut tight with nobs was found open twice today and later tonight I was in bed watching tv when both of the closet doors were jerked open fast from the inside. I checked everything and it was impossible for both of the doors to open at the same time. Considering that lately I felt as if someone was watching me in my room and I got a sudden chill and cold after I checked the closet I decided to call a friend and she knew what to do.
I salted all my window panes and put garlic in tied cotton thread. I lit candles and incense as well. While I continued to text my friend, my satellite and wi-fi shut off suddenly. The weather was fine with no rain or wind and everything was off for 15 minutes. I kept trying until I got service back and my friend sent me screenshots of messages saying I blocked her and my calls were blocked too. I explained what happened and I didn't block her.
All of these things have happened but it's not the first time. A lot of things have happened since my friend died and even before that. If he is trying to contact me are these signs safe? Would I know it's him and it's safe to respond or would it be something else. Nothing dangerous has happened but the signs are strong and impossible to ignore and I don't know if I'm safe to contact his spirit or if I'm being tricked.
I genuinely want believe it is my friend since the physical contact was not harmful and did not seem wrong but it also feels out of place for a loved one to do this to me after so long. A lot of the same stuff has happened to me in any house I've moved to or visited since he's died so I'm started to believe the houses aren't haunted but rather I am. The feeling of being watched and bothered has also happened in my childhood before my friend died.
Those signs seem odd to me. An encounter with a loved one, shouldn't feel like this. You said about sudden cold and the closet doors. Those don't seem like signs from a loved one to me, they seem to have something else causing them.
Maybe you had an attachement all your life, and being vulnerable at the time of your friend's death, it just got something to feed on.
Take care. I don't think that communicating is a good thing though.
