false awakening

I vaguely remember a total of five different dreams. One involved going to the dentist, but I don't remember anything more about that.
Another takes place in a mansion. I'm not quite sure what, but we are investigating something (again, not sure who 'we' is). Perhaps the murder of a middle-aged/old woman, with short dark grey hair, who seems to feature in this dream. There is also a place we go to think about information we've gained while in the mansion or surrounding grounds; it is a grey, mottled place with no horizons, set with a number of portal-like occurrences, which are either pale salmony pink or light blue (could be either. Don't remember which). When we enter any of the portals, we are taken back to the mansion.
A third dream takes place in a jungle or forest, with a rushing pale blue river. There are groups of people, none of whom I know, and I am put in a group with them. We all receive 'skills' which appear as pale dotted markings on black spheres/circles. Now we have to cross the river/work our way up it (don't remember which - something to do with the river) but to do so, we have to choose new groups. Nobody wants me in their group. This may be because my allotted skill is useless, or because I don't particularly want to join in. I end up in a team because someone whose 'skill' appeared as a pink scorpion engraved on a black sphere grudgingly allowed me in.
In the morning, after I wake up, the only dream I remember at first is the investigation dream (I guess that was the dream I had woken up from), but I rapidly forget parts of it, such as what we were investigating. I spend a moment trying to remember parts of it, with a limited degree of success, and decide I need to write it down quickly. However, I don't, and without realising it, fall asleep again, in which I dream that I have written down my dream. Sadly, by the time I wake up again, I forget even more of the dream, although I can now remember the rough theme of the dentist dream. Now I really need to write it down, but fall asleep again (did I ever wake up from the first dream which I write down my dreams in? Perhaps it was a false awakening). Again, I dream I have written down my dreams and begin to sketch the woman from the mansion one. I wake up for the third time, pick up my notebook, do a reality check and write down my dreams. Half way through, I remember the jungle dream. Later, when my mother is making me a coffee, I remember another dream. I remember the details of this one;
My friend D has brought in cakes and sweets to sell at charities week in the auditorium. I don't buy anything until later, when there are two plastic bags full left. D's stall is set up near the front of the hall, about level with the speaking podium, and comprises of one blue table which is longer than those in real life. I check the bags and see in the one on the right side a box of cakes and ask to buy them. 'You can't buy the whole box' says D. I say that I want to, or something like that, and later, we walk from the auditorium of my current school to the year six classroom of my primary school. Here, we sit on a desk in the room which we weren't in in year six and I ask D how much she wants for the box of cakes. She says £3.75, and I'm not sure I want to pay that much. I have my handbag and have been holding about four pounds ninety in change in my hand for a while now. D leaves. I open the box (which is light blue) of cakes and look at them (I still remember the layout), eventually deciding I don't want them all after all. Instead, I decide to buy a pain au chocolat and put dibs on the éclair when D comes back. Dream ends before she does.
