Hereditary Insanity

My name is Effie and I'm 16 years old. All throughout my childhood bizarre events have occurred and I would like to know what you think about them. It started when I was about 2 (although of course I don't remember this) when I was in the back of the car my parents were driving. I had never been where they were taking me, but I pointed down roads to where certain landmarks were and seemed to know exactly the turns they'd be taking. From the age of about 4 (my earliest exact memories), I seem to have been able to hear things with no origin. I used to stand in my old kitchen and swear I could hear cupboards slamming and people arguing, even though my parents were perfectly quiet and watching the TV. I've also always had premonition-like dreams, the most serious of which involved lots of fire and people screaming and me waking up at exactly three minutes past six in the morning- I found out later an oil rig had exploded at that precise time. The less serious dreams involved school trips, birthday presents and the clothes my mum would wear the next day.

As I progressed into my teens, things seemed to get worse. I became much more aware of others around me, gauging their intentions and personality without having to speak to them. I have been 'visited' in my sleep by people warning me of things, and I know for a fact my bedroom isn't a friendly place. My mum (we're been talking recently and she has experienced almost everything like me, except her 'ability' got worse as she grew older, and mine seems to be getting more intense) said she would never want to spend a night in my bedroom, and I can agree- it feels like an unpleasant place, although the rest of my family have no trouble in there, but my dog won't hang around for long.

I'm a fairly rational person, but lately, I've been terrified of the dark. It's almost like someone is there with me when it's dark and I can sense their pain physically- I'm having panic attacks if I stay in the dark too long. I've seen people who don't exist and I think my childhood 'imaginary friends' were a lot more real than I realized.

Something else notable is that my nana (my mums mum) was admitted to a pschiatric ward with similar imaginings and paranoia. I don't know what to think, but I'm petrified of the thought that I could be going insane... What do you think?

Please help, I don't know what to do.
