Searching for sleep – there’s a special delight when you start detecting light at the end of the tunnel (rather, lack of it). When your thought stream switches from say, thinking about personal Gods and intervening Gods to thinking  a lemon fruit is that God . 😀 This, I call a drift indicator. Another indicator that I’ve had often is the riding-a-bike feeling. I’m sure all of us have some kinda indicator or the other each time. I wonder if some of the indicators can be recovered and described at all. The weird randomness, in this case – the lemon, is a feature thats amplified in dreams. Ofcourse, while in a dream, the weird randomness is no more weird or random. Its deceptively real – either convinced of/oblivious to it. Only on recollection does the weird randomness surface.
After reflecting on this weird randomness sometime back, I’ve had a couple of dreams where I question the reality of the dream within the the dream. But I think this has to do with the variations of levels of consciousness – where I drift out and back in. I’ve had dreams (and I’d guess many have too) where continuity is maintained even after such a drift out and in.
 I even wonder, if thinking is the right word here. More like, sampling or observing.
