Astral projection is the ultimate form of transportation and, as with any kind of travel, you need to pack some kind of travel alarm clock. This is even more important in astral projection than in more conventional physical travel. In astral projection, your spirit cuts loose from your body. Generally, you want to be able to find your way back to your body, other wise you'll be, technically, dead. This is why shamans form the caveman days used some kind of astral projection alarm clock.

Human Assistants

It is dangerous to astral project on your own without having an astral projection alarm clock in some form set up in advance. Usually, you can have a friend just keep an eye on you. Shamans and native healers undertook astral projection ceremonies where they had at least one helper. If the master was gone from the body too long, then the helper acted as an astral projection alarm clock to get the master back.

An astral projection alarm clock need not be high-tech or fancy. In some instances, an assistant banged a drum to wake the master back up. In others, the assistant would lean into one ear and kindly request the master to remember his or her life here on earth and come back into his or her body.

Spirit Guides

Not everyone can learn the ability to astral project. Some are seemingly born with the ability and they became shamans in their tribes immediately, even if they were completely unrelated to the present day shaman. The shaman would find young people with the ability ad train them to move about in the spirit world for the benefit of the tribe and not just themselves.

And many have to learn how to astral project, with varying degrees of success. Some astral travelers report being met by their personal sprit guides or ancestors or guardian angels and these spirits acted as their astral projection alarm clocks. It would be the spirit guide's job to not only let the traveler know when it was time to go back inside the body, but helped him or her get back.

There are little kinds of clocks sold called projection alarm clocks, but all that means is that they act as a film projector, showing the time or soothing images on your walls or ceiling. They have no known properties to assist anyone with astral projection, although a loud alarm could theoretically help your spirit find it's way back to your body.
