I read this recently when researching the difference between being asleep and being awake: " Dreams are totally devoid of proof and validity. Reality, on the contrary, is the basis of validity." How absurd a statement? Surely that when dreaming there is proof and validity of all things within the dream and NONE of 'reality / waking state'. And of course vice versa. I have lucid dreams and water is wet, the wind is draughty, the cake is delicious, sex is amazing ... . What is interesting to me about dreams versus waking state is this (please share your thoughts as to why this might be): I have NO memory of my waking life (neither that of my true self, my name, age, where I live, family, ...anything at all) when I am dreaming UNLESS I am lucid dreaming and even then my recall of what life is like when I am awake is not accurate or complete. Why would this be? As an example, I recently became lucid in a dream and took the opportunity to fly out my bedroom window, over the neighboring garden to 'investigate' my dreamscape. I thought in the dream I was accurately recalling my waking life surroundings. However, when I awoke, I realized the gardens I was seeing in my lucid dream state were nothing at all like how they are in 'reality / waking state', and yet even though I was lucid when dreaming, I was not aware of this discrepancy. In other words, my 'memory' in my sleep/dream state is not the same memory I have when I am awake. A question arises from pondering this, are my dream memories consistent at least within the dream. Ie when lucid would my dreamed garden take the same form each time, just as my waking garden does? The interesting thing about this is yes, pretty much but not always.
