First clear it up, title should have 'Of' between 'String' and 'Dreams'.

I have had about 4 dreams of the same nature across the past 4 nights of sleeping and am trying to figure out why. They are quite odd and I really am not sure what they mean so some help would be appreciated.

1. I had a dream that I was in a main, round room that had 4 different branching rooms connected to it. It was a large dome like structure and each of the rooms were bedrooms. I was confused as to which room I should enter. My mother was in a corner of the main dome washing dishes in a sink. I walked up to her and said "How are you going?" and she responded with "Good". I then for some reason immediately knew which room to take and entered the room that was farthest away from my mother. It was a very small room that had 4 beds in it. They all had the sort of coverings you see in hotels. 3 were singles and 1 was a double. I chose to go to a single bed and pulled back the covers and layed on top off it. I then proceeded to wet the bed even while I was awake and fully clothed laying on the bed. Then I woke up.
2. I dreamt that I was in an institute which looked very similar to the University of Canberra and that I was part of a group of six teenagers (including myself) who were falling a man and a women in Labcoats. There was me, a guy, two girls and three other guys.. There was no one else around and I walked at the back of the group. Somehow I knew that the other teenagers were incontinent and on two of them (the 2 girls) I could see the plastic backing of diapers sticking out of their clothes. I knew that I too was incontinent, but was only lightly urinary incontinent, a fact which I seemed quite proud of; and I noticed I wore a thin slip on diaper. We followed the two scientists to a dam (in real life there in no dam remotely close to the Uni) which was just in front of the main building and ringed by the type of sand you find at a beach. The scientists told us to "Go play" and we all went in the water and splashed each other, still in full clothes. I then walked out of the water and decided to play in the sand for a while, but the other teens remained in the water playing. The two scientists were at the top of the hill watching over everybody. While sitting on the sand I decided that I wanted to be fully incontinent like the rest of the teenagers and resolved to be just that. We all then began to walk back to the main uni building which was right next to the dam and I could hear the two scientists arguing. This time I was at the front of the teenage group, but still behind the scientists. The man said in an annoyed tone, "Why did he become incontinet? He was fine earlier." I realiaed they were discussing me. THe woman replied, "It's fine really. We'll just treat him exactly as we treat the other children." For some reason I then realised I was now in a very thick, proper diaper like the rest of the children and it was very wet. This made me immensely happy and I then skipped towards the front doors, past the scientists and almost made it before waking up.
3. The first thing I remember in this dream is appearing at school (my current final year school) and I was thickly diapered but had no pants on, only a shirt, which did little to cover up the diaper. I knew that someone had put it on me earlier but I didn't know who. I began to walk through the school, next to someone else but I couldn't see him or really focus on him. He was only in standard school uniform, of which I was jealous. As we walked through school the standard thing you'd expect to happen did and as I came close to other students who would say things like (I noticed only the girls would talk, the guys would stay silent but watch) "Diaper butt", "Ooh baby" and "Does baby want a change?" As we proceeded deeper into the school I realised I had to wet and just let it out without really thinking, I was wearing a diaper after all. Apparently this drew my a bit of attention from a group of four girls nearby who all burst out laughing once I finished. FInally I got to our main hall where I knew the person who could remove the diaper waited but just as I reached the doors I suddenly appeared in a small room with a matress in one corner and a door in the other. Those were the only things except for a window which I couldn't see out of. I was diapering myself on the floor when someone put their head in the window and saw me and looked suprised. He then withdrew and I stood up and looked back through the window but saw no one but a long hallway with a tiled kitchen at the end of it. Relaxing, I then finished diapering myself and in only a diaper and shirt I got into bed and lay down. I knew that if I wasn't diapered I would wake up with a wet bed and was satisfied that now that I was diapered this wouldn't happen. I noticed the bed was merely a mattress with a quilt on it but didn't find that important. I was very glad that I was wearing thick, protective diapers to save me from a mess upon awakening and I slowly drifted off to sleep. Then I woke up.
4. I was in my bed and was half asleep. Then I began to wet the bed and could really feel like I actually was which I immediately thought meant I was wetting my real bed. I then woke up and everything was still dry.

I didn't wake up wet after any of these dreams and am not quite sure what to think.
Anything I left out just tell me and I'll inform you of it.

Well, since the common theme of the dreams is wetting yourself like a baby, the first thing to do would be to make sure that there isn't any physical problem going on.

Uncontrolled urination in your dream could mean that you have something toxic in your life that has been building up and getting worse - a relationship, a memory, etc. - and you have to get it out.

The association with babyhood could have to do with the idea that if you decide not to tolerate this thing anymore, you will be behaving immaturely - a grownup just learns how to cope with things no matter how bad they are, and a grownup doesn't let difficult feelings come to the surface.
