Dreaming during his dream state

The individual soul does not know that he is dreaming during his dream state and is not conscious of himself as he is bound by the Gunas of Prakriti. He passively beholds the creations of his dream mind passing before him as an effect of the workings of the impressions (Samskaras) of his waking state. - Swami Sivananda

I always woke up from drunk dreams

During my first decade of sobriety I always woke up from drunk dreams with a feeling of gratitude that it was just a dream. But the feelings seemed so real. From the cold droplets on the brown beer bottle fresh out of the freezer where I used to chill them up, to the life giving rush of a blast of cocaine, the experiences were totally convincing. I always feel a little doubt about the commitment to recovery when this happens. But I'm normally relieved to wake up and realize I'm really still sober.

Touch the dreamers’ chest with the point of a pin

If you touch the dreamers’ chest with the point of a pin, he may dream that some one has given him a severe blow on his body or stabbed him with a dagger. - Swami Sivananda

Very little sleep and sit upright

Buddhist monks or yogis sometimes participate in long retreats with very little sleep and sit upright in a meditation
posture for 24 hours a day for considerable periods of time. In that situation, the sleep is very light and one never
goes very deeply into unconscious states. Obviously these practices are very intense and not particularly designed for lay people like you and I. They may not really mesh with living fully in the "world" as we do.

Dreams very confusing

In the treatment center in Fall 1984, our counselor told us not to be alarmed if we had dreams of drinking and/or using drugs. He referred to this necessary part of recovery as a "flushing of the psychic toilet." When I got my 30-day sobriety coin at a meeting I talked about my own drunk dreaming during the hospital stay. An old-timer shared that he'd been sober for decades and still had them too and that it was OK. What a relief! I'd worried it was because I wasn't serious about my recovery, as if these dreams revealed some secret desire to get loaded. But I really did want to stay sober, which made the dreams very confusing. - by: Darren Littlejohn; from:The 12-Step Buddhist: Why Do We Have Drinking Dreams?

Sounds cause very elaborate dreams.

Certain kinds of external sounds such as the ringing of a bell, the noise of alarm-clock, knocks on the door or the wall, the blowing of wind, the drizzling of rain, the rustling of leaves, the blowing of the horn of a motor car, the cracking of the window etc., may produce in the mind of the dreamer variety of imaginations. They generate certain sensations, which increase according to the power of imagination of the sleeper and the sensitiveness of his mind. These sounds cause very elaborate dreams.
