Hearing Different Voices

I have always had strange things happen to me like most people on this site. This is also my first post as I am hoping to get some sort of answer to what has been happening lately.

Some times, I hear voices. I've battled depression for several years and when I'd go see therapists, they'd blame it on chemical imbalances. I highly doubt it. I'd heard them coming home from school in highschool. I'm 19 now and in college. It would sound as if a tv was on in one of the rooms in the house. I would check each and every one, and no tv was on when I checked. I always remember that a woman's voice would over talk the rest of the voices, but I could never understand what they were saying. I haven't heard them since. I've been on different types of antidepressants but recently cut them off cold turkey. I've always wondered if the medication caused me to stop hearing those voices.

Now recently, I hear voices inside my head. Not in a crazy sort of way, more of warning type thing or information is being told to me without prior knowledge if that makes sense. Like people will say something and I'll randomly cut them off, as a word, phrase, or sentence just flys out of my mouth which I never could have known, with the information they were about to say. It's like knowledge from an unkown source sometimes whispers things in my head and It'll come out of my mouth.

Another example would be during my freshman year of college I was down stairs cleaning by myself and I was standing at a sink staring off at the ceiling. A few minutes later a small sexless voice whispered 'A spider is about to crawl out below you' absentmindedly, I had asked where. 'Under the sink.' And as soon as I looked down towards the sink, a huge black spider came crawling out. Mind you, I'm terrified of them. All I'd like to know is, am I some kind of psychic? Many a things have happened to me other than those occurences, but these are the ones I am more concerned about. I'd really appreciate the help.

Thank you.
