I am not entirely sure where the idea that dreams are downloaded on the way to waking up came from, but this is one of those things that, while our science has not revealed exactly the nature and reason for dreaming, has been documented. We dream for sometimes as much as 2 hours a night when we are healthy. All dreams do not take place in one specific instance, such as the moment of waking up, and there is brain activity specific to dreaming - it is partially a physical process, which is where one might say we engage the physical filter.

That said, outside of the physical being there is no such thing as pleasure or pain, no experience is either joyous or terrifying, because these are physical expressions; without a physical frame of reference we can't have a concept of these things because they rely on a context of sensation. It is important to identify and recognize the difference between the chemical/electrical nature of our physical being, and the ineffable, intemporal nature of our spiritual being. All experience is equal to a being with no sense of temporal continuity or spatial divisions. One could say that the physical aspect of our existence is the only context we are able to have when dreaming, and that all dreaming is a joyous experience only when we are able to center our awareness in the spiritual experience of being physical.

It is pointless to try and distinguish whether a dream is a 'bad dream' while dreaming or only after waking up. However, it may be simply that your experience in incomplete. I know I have had good dreams, usually very stimulating dreams, where I have awakened suddenly while in the midst of it. There is actually a very direct explanation for this. While dreaming, you're in a kind of paralytic state so that you don't run around your home in your sleep acting out the actions of your dreams. People who sleep walk, for instance, haven't had this process engaged properly, one of the several reasons this phenomenon happens. However, you still have access to most of your functioning brain - so that while dreaming your breathing and heart rate can change, your body may have spasms in response to physical reflexes engaged in your dream, and the whole spectrum of chemicals typically present during waking consciousness, including adrenaline, can be excreted by your glands while dreaming as well. Enough adrenaline, and you will wake up whether it is a good or bad dream.

While the spiritual and psychological aspect of dreaming is largely a mystery, and it's actual purpose is somewhat of a mystery, the physiological processes are not a mystery at all in terms of academic knowledge. The processes that occur and the reported correlation between dream experience and observed changes in the body is fairly thoroughly documented and still a subject of much research, largely because there is a great question being asked by all researchers summed up as, "Why the heck do we dream in the first place?" While scientifically we are not close to answering this question, it can be said that there is nothing mysterious about why we wake up during some dreams and not others. It's simply a matter of stimulation threshold under different circumstances.

Accepting the word of channeled entities is a risky endeavor. Never allow your own reason to be superseded by these types of people for two reasons: One, it is impossible to confirm that an individual is actually channeling a being from another planet/dimension/density/etc.; and Two, it is unreasonable to assume that because a being exists at a higher density/dimensional complexity than we do, that they have perfect knowledge of experience on our level. It is widely believed that higher dimensional being have an inherent ability to know the lower dimensions with some degree of perfection - and yet much of what the various entities supposedly say is not consistent with what all of the others say. One of the two above reasons must be true because of this.

when the body sleep the spirit travels. when the spirit download back in the body the mind know about it. when you are lucid the mind is still link with the spirit. so the download is automatic. experience and enjoy.
