Whacked out recurring dreams

One of the reasons I joined up is because I keep having some weird dreams. Well, I'm always having weird dreams but the following ones are quite emotional ones.
Anybody in the UK, or Australia, who watches the program Neighbours will know of a character called Bridgette who had a baby and died in a car crash.
Well this is the thing. I had this first dream about a month ago. I dreamt that Bridgette had died and I was on my own with the baby and I couldn't cope. I kept thinking of her, how I missed her and how I was going to cope bringing up a baby on my own. When I woke up I was quite disturbed by this and was upset. When the dream is happening, and even when I have woken up, it feels like a reality and not like a dream at all. Now, I can't remember much about that dream because it was a fair few weeks ago and I just told myself to forget it and move along.
However, last night I had another dream about Bridgette and the baby. It was something along the lines of my being left holding the baby. Whilst I was holding the baby I was thinking to myself that she had had the baby with another guy and it wasn't mine. However, I couldn't remember (in the dream) whether I had had sex with her or not and whether the baby might be mine.
After that (my dreams are very patchy) I can remember thinking happy thoughts of her and us being together. I then felt the urge to try and get some info about her and I needed to find her (even though she was dead) and I so wanted to be with her. I remember going in and out of buildings, waiting around in the hope she would appear. The next thing, I remember walking along a street with a row of old terraced houses. I knock on one of the doors and go inside. The woman inside claims to be my great-grandmother. The woman I know as my great-grandmother (who incidentally died 11 years ago) was there but a younger woman (late 50's) was claiming that in fact she was my great-grandmother and showed me her birth certificate.
The next thing I know I am on the run from something or someone. All I can remember is free-running (parkour to some) off buildings and roofs and along corridors. I eventually end up in a library. I know I have to find/tidy up some paperwork of mine that has been there since my childhood. I look at all the bookcases and I am shocked. And this is the weird part. I am convinced that the bookcases are the one's I have had when I was a child at my first home. Except I never had bookcases as a child. I am desperate to find Bridgette...

... that's when I wake up. However, I am still convinced when I wake up that i am missing some bookcases. I need to know where the bookcases are with some urgency. Now, it is 19:17 in the evening. I have been awake nearly 12 hours. Even though I'm fully awake and can rationalize my thoughts I still get some sort of thought in my gut that I own these fictitious bookcases.
What is this all about? The bookcase thing has got my freaked out but also the thing with "Bridgette" and the baby and I want her and the baby to go away. I don't like these dreams. I get very upset over it and I don't want to get to the point where I am too scared to go to sleep. It upsets me because they seem so real in the dream and when I wake up there's still a part of me that believes that they are real. Is there anyone out there that can help me understand what is happening here? I'm going nuts over this one.

Looks like no one has ventured a stab at your problem due to its complexities. And I hate to see a person ask for aid and not to recieve, but here is my unprofessional advice/ramble;
That appears to be a very personal related dream, nightmares and recurring dreams can have many base attributes from fear of the unknown, or specific fears such as claustraphobia, fear of imminent "bodily" harm, and fear of loss. Though I am no psychiatrist or hold any form of academic achievement. Nightmares are a topic that interest me and it is from my own personal experience that nightmares are reflective of "you" personally that I will attempt to help you answer your question.

Your dreams appear to be loss related dreams that are quite upsetting to your particular personality or mindset. To understand what is happening you may want to take an internal stock of what values you hold dearest, and which values the dream offends, and what response you should make in retaliation. Dreams can be a learning experience, as well as a self help tool. At the basic line, there are no physical missing bookcases, "its all in ya head jack". But just because there is no physical missing bookcase, does not mean it is not real. To answer your question of "understanding what is happening" I can only hazard further that your mind may be seeking a solution to a specific problem you fear you may face. It may be upsetting, you may feel annoyed you are fixiating your mind on this "stupid dream" you might call it, but it is your response to this event that determines the outcome, whether a satisfied conclusion of the recurring dream is reached, or it continues until you either forget, or move on. A month is a lot of time for a dream to idle between manifestations. They usually dissipate mostly from memory after a time, again relative to a person, this is a notable fact.

Speculating far far out here:A bookcase is synonymous with knowledge, and you seek a dream character for knowledge. it could be this loss of knowledge, you feel a part of yourself has died? if you have recently lost a loved one I would be inclined to think you fear losing your memories of this person. Dreams are tricky buggers to pin down!

That is all I am able to glean from your writing, I hope in some way I have aided you in understanding your dream. One point I am confused with. Did this Bridgette character die, or the actor die, if so my last point may be relevant, if it is not, I just wonder? Maybe it will simply blow away. Such complexities in a dream tend to be very fragile, the mind requires sleep for recuperation, not to maintain drama
