Any dream vivid and full-bodied (more than daily), in every dream there is psevdoberemennost that the dreamer acts on its behalf and with the help of the personal will.
Only the vast majority of cases, immediately on awakening forgotten about it (well, don't need brain). Exceptions are just lucid dreams and just caught something:
first due to the fact of awareness: consciousness is transferred into a dream, and with it switched and attention is activated more superficial layer of memory and after you Wake up information about sleep is lost much more slowly.
second because of the resonance with dominant thoughts: waking up, the person clings to the burning topic and spins a large share in the dream of information.
Brightness and clarity (vergleichstest) do not occur in the dream from the moment of realization - they are always present, but the vividness of memories begins with the moment of awareness.
It's like beach volleyball - while watching from the side, lying on the sand, it is not deposited in the memory - after a couple of hours to retrieve from memory you will need an external stimulus, but it is worth to raise the carcass and sweat, chasing after a ball (or accidentally get hit in the head from playing) and the memory will retain the individual episodes for much longer (and a few years of external stimuli will easily raise the fragments of memories about this game). Consciousness is always much easier to remember what they were directly involved.
Therefore, it is necessary to divide just vivid dreams and lucid. I think in this case, the dream was not lucid.
