Recollections from the past few years. Am I mad?

Hi folks I have read as much of your site as I can but I am still not sure if I am totally insane or not? I would like to explain to you what is happening to me and if you have the time you can read it and then perhaps just drop me a quick line just to tell me if you have heard of anything like this before as I am starting to feel a little out of my depth…
A brief background about me, had a pretty unstable childhood, parents were a nightmare. Had reoccurring dreams as a child all were centered around an unpleasant figure in my room (I never paid any attention to this). Teenage years were also a bit turbulent but don’t remember anything weird in the way of dreams or seeing anything.
I put myself though university, have a degree in Zoology and a masters in genetics. I currently work in Developmental Genetics for the Australian Government.
Now about 8 years ago I started having dreams that there were hooded figures in my room at night, these dreams were not common, I recall only 1 or 2 each year. At first they were very hazy fragmentedmemories then as the years past they became a little clearer each time I had the dream. About 5 years ago I recall being laid in my bed unable to move anything but my eyes, I sort of recall a strange light but not clearly, I could see maybe 4-6 small beings around the bed but could not see their faces. I recall being taken to a vessel of some sort, there were no sharp edges on anything in the ship (I don’t know why I recall this but it stood out) and it had an almost mother of pearl colour to it, blue and purple. I remember climbing off a table, not really afraid, but trying to get off the ship, the small beings followed me around and sort of ushered me to a room. Then I woke up in my bed, exhausted and a little nervous, I woke my partner up to explain the odd dream I had and before I even said anything she said “I just had the most bizarre dream that there were 6 small creatures in the room, and I couldn’t move, it was ok I wasn’t scared because they told me they were here for you!” This did not bother me as much as it should have but it certainly made me think that perhaps my dreams were not just dreams.
I had these dreams on and off for the next few years but noting quite as eerie as that one. Then I started hearing voices in my head, not weird voices just a voice that could be described as my consiousioness telling me things that would occur and when (and they always did!). Then I had dreams about major world events and it all got too much. One day I was at home and the voice in my head started telling me things and I had enough and screamed for it to stop, it stopped immediately and I have never heard it since (I must say now it is gone I rather miss it). I saw a doctor about my dreams and voices and they said I had bipolar disorder and prescribed me lithium, after 6 months I stopped taking it as it made me feel dead to the world and I have always felt very connected to it, I hated that feeling. Now in October last year I was at work at about 6pm and all of a sudden I felt I had to go home to bed, this is most unlike me. I grabbed my stuff, got in my car and went straight home to bed, and fell asleep immediately. Guys this is the coolest “dream” I have had to date, I woke up and my room was just as I left it, I hadn’t even pulled the curtains, the room was filled with this amazing blue light which itself seemed to be full of bright blue orbs dancing around, I cannot describe this light it was just something totally different and so utterly fantastic, I knew what was happening and I even managed to calm my breathing and my heart rate. There were a few small beings near me but again I could not see their faces its like they are masked from me, I felt myself being moved and then I remember nothing until I am back in my bed, the light is fading and I am desperately trying to see the faces. I remember thinking “I want to see you”, and at that moment I saw what seemed to be a creature outside my window (I sleep upstairs so this seemed very odd). I got the fright of my life! It had what appeared to be quite big black eyes but its face was not smooth it was wrinklyand it stared at me for a short while (ugly fella this one!). I lost my calm and started to panic, something I am still angry with myself for. I wanted to smile at it but I was too scared (this is frustrating for me as I am not generally scared of this stuff). This dream was very very real. Since this dream I have found myself becoming more and more detached from my life and people around me. Its almost like my mind is straddling 2 different realities or dimensions, its very odd. People are becoming a bore and frustrate me and I crave the company of like individuals (I have met none!). I have been told that people can feel me vibrating when they touch me. And sometimes its like I can feel the earth herself breathing (that’s not exactly what I feel but I cant really explain it any other way). Since this night I have had many sightings of strange lights in the sky (witnessed by me and my friends so I am not imagining these at least).
This sort of stuff would be fine if I was a hippy sort of bloke, but I am a scientist and its sort of hard to get my head around. I was really hoping that perhaps there are other people that have experienced something like what I have explained, I am concerned I am going round the bend, perhaps even totally nuts?
Thank you for your time, I am sorry to be such a time vampire.
