There are many levels to what happened here. We must bear in mind that the phase is not a fixed state. It tends to fluctuate between wakefulness, dreaming and unconsciousness. Our goal, of course, is to maintain a steady and enduring optimal phase state - this comes with practice!
Setting the simulated phase phenomenon aside, it is also possible to have full-fledged phase experiences and have a poor recall of them. If this is the case, then it is wise to start recording ordinary dreaming in a dream journal as this will promote an excellent memory of conscious experience during sleep. Undeniably, a good memory of dreaming boosts your chances of entering the phase via dream consciousness and will also help you to have a good recall of phase experiences themselves. Here's a relevant excerpt from the "Lucid Dreaming" section of this site by Michael Raduga:
"...there is a direct correlation between the number of dreams remembered and the probability of becoming conscious while dreaming. That is why developing the ability to remember dreams is crucial. In essence, the ability to achieve dream consciousness rests with the conscious mind, which is very much interconnected with memory-related processes.
Consciousness is naturally inherent in dreams, but it lacks rapid, operative memory. Dreamers may know who they are, their names, how to walk, and how to talk, but may not know how surrounding events are related, or the nature of their significance.
By increasing the frequency of remembered dreams, short-term dream memory becomes more developed, which enables more realistic dream experiences followed by a higher probability of dream consciousness.
There are three techniques dedicated to increasing the number of remembered dreams.
The first is to simply recall the details of dreams upon awakening. Within the first few minutes of waking up, try to remember as many dreams from the night before as possible. This should be done with a great amount of attention and diligence because this exercise strengthens the memory. If possible, during the day, or, better yet, before going to sleep at night, recalling the previous nightâ€™s dreams once again is highly beneficial.
Writing dreams down in a special dream journal is much more effective than simple recall. Record dreams in the morning while memories are still fresh. The more details recalled when recording the dream, the better the ultimate results. This is a very attentive approach that demands a higher awareness than simple recollection. Writing dreams in a journal significantly increases awareness of actions and aspirations."
