When I was a slight bit younger, I used to hear someone I know say something, even though I was in an empty room with no one else in it. I think it was only when I was living in a certain house, my only memories of it happening is in that particular house, upstairs in particular, and only when I was alone in upstairs. I would hear someone I know say something, as if sort of from a distance, and then I would yell out to my mum but she wuld say that she heard nothing at all, and that no one else was in the house. The real amazing thing was, that whenever I heard such things, like a week or two later, the person I heard would actually say that same thing for real. Any explanations of why this happened? Why did this stop happening?

One strange thing that happened recently, something that really scared me. I felt this really terrible feeling, like my depression had suddenly returned, and felt a huge need to sms one of my closest friends. So I smsed her to tell her that I was feeling really terrible and like I was sinking into depression again, and she smsd back to tell me that someone she knew died in a car crash recently. I hadn't heard about the death until then, this really scared me, like depression can return at any time, but a few seconds before finding out about a death, combined with an urge to text a friend who knew the deceased? Only other time that I have gotten a bad vibe like that was when my parents called me into the living room, to tell me that my grandad had died. Is this just normal coincidence?

I don't know, I just want to talk about those 2 events, try to make some sense of them.

You are not alone. Recently, a close friend of mine had been weighing heavily on my mind for about a week. When I finally got around to calling her, I learned that she and her husband had decided to get a divorce. This knowing about others without being told the information from them happens now and then in my life. I really think that we are all connected spiritually, especially if we are close as friends.

Sometimes you may be more perceptive as a child or when you are younger, which may explain why it doesn't happen as frequently as it used to for you.
Though one thing to remember is that it may be coincidences, but I don't think so because people that tend to be more sensitive experience these depressions and gain a knowledge of their sixth sense. I have researched a lot of this because I used to have dreams about people that I knew the night before they die and then the next day find out they are in fact dead. Some people like us, take time to feel things more and therefore are more sensitive to it.
You could also just be able to feel things as they are about to happen (the having of a bad feeling). This could happen when we are close to some people or we are in the situation ourselves, and we are more attuned to this because our thoughts are in a flow with theirs.
