Welcome!

First off all, let me just be sure of one thing: you see dead people during the day or in your dreams? Because if it's the first you realize that we're not going to take that very lightly, but more be a bit concerned with your well-being. Even though I don't believe in any of the "psychic/medium" claims because no one has ever proven them in controlled settings, I do think you should consider talking to a psychologist if those events are bothering you. I'm not saying you're wrong for sure, but have you considered that you might have some psychological problems that are putting a great deal of stress into you? I had a friend in a related situation and it turns out that the "psychic" explanation he gave to the events was nothing more than it's own subconscious trying to justify in any way possible the reason for his chaotic/random thoughts of everyday.

The community around here is extremely friendly and I'm sure you'll be able to find people to help you with in terms of sharing your experiences, but please consider that might be an alternate explanation to your issues. Writing this solely for the purpose of hopefully throwing a different perspective on the subject, sometimes the answers we seek might be far more simple and less mysterious than we think
