Spiritual Guidance In High Dream

So I haven't been sleeping too well the last few nights. I was smoking earlier today, and I laid down as I was feeling fairly tired. I entered into a dream, and yet the high seemed to somehow carry me through into the dream more smoothly than usual, such that it didn't exactly seem like a dream. Anyways, in this dream I was just at home, and I was extremely high. It also seemed that I was truly being thrown into mystical perception.
 
Now it was clear what the cause and essence of this spiritual perception was. It was experiencing and perceiving without context. In other words, no ideas in my mind about where I was, who I was, what I was doing. This would make me nervous at times, and I would scramble trying to answer these questions, and I was able to, but it required real effort. It was so much easier to just stay in that mode of perceiving where there was no context to anything. The idea was just to forget virtually everything, anything that could possibly create a context for what you are experiencing. Like this was the key to accessing higher states of spiritual consciousness.
 
It just reminds me of a quote I vaguely remember from an eastern text, though I cannot recall whether taoist, buddhist, or hindu. It was something like, 'the greatest joy there is is to forget everything.' That is a paraphrase from inexact memory, what I specifically remember as being the main thing was the 'forget everything.' So, any thoughts on the experience, and its message?
