Charmed: Astral Projection

Astral Projection is the ability to project one's consciousness into an astral form outside the body. When a person astral projects, their physical body falls to the floor, slumps over or remains still until they return.

While in "astral mode", powers are dormant. However, some advanced users have mastered the skill to use their powers whilst astral projecting.

Types of Astral Projection
There are two types of astral projection:
 * Projecting yourself onto the physical plane with a corporeal body.
 * Projecting yourself onto the astral plane as an invisible spirit.

Corporeal form
This form of astral projecting allows the user to interact with other people and vice versa. In Prue's case, Telekinesis is used to move her astral form outside the body and to keep her in "astral mode". Because of this, she cannot use Telekinesis during the projection. However, this limitation can be overcome after excessive exercise with the power. Though her Telekinesis is neutralized, she still demonstrates the basic witch ability to cast spells.

When astral projecting, the user's body will become unconscious. When new to the power, the body will collapse and fall to the ground, although, more experienced users will be able to let their body stand still.

This form of Astral Projection is most common for beings such as withces and can be recognized by a pink flash that accompanies the projection when it appears and disappears. Demonic beings astral project with another form, an invisible form.

Invisible form
This form of astral projection allows the user to appear invisible and make a telepathic connection with someone. While in "astral mode", the user of this form can implant thoughts and suggestions to other people. The suggestions can be heard by anyone or by an individual, depending on the concentration and strength of the user.

Barbas is a prime example of demons who use this ability. He learned to astral project from another demon, whilst in purgatory, in return for that demon's freedom. Together, with his power to read fears, Barbas gained much strength over his victims, allowing him to plant subliminal thoughts into the mind of his victims and creating illusions. It also allowed Barbas to attack and manipulate his victims without them ever knowing that he implanted any thoughts, as well as attack them from a distance.

Exhaustion
When new to the power, astral projecting can be exhausting for its users as it requires a lot of energy to maintain two corporeal selves. This also causes their astral selves to not last very long. Over time, users will master the skill to use their ability without fatigue and maintain an astral self for a longer period of time.

Very advanced users will even master the skill to be awake in both their physical body as well as their astral form. However, this would require a lot of energy, exhausting even the most advanced users.

Teaching Astral Projection
Astral Projection is one of the few (if not only) powers that can be taught to those who do not naturally possess it. However, spells and potions are favored for those who do not possess the power and do not have or want to take the time to learn this ability.

In 2001, shortly before her death, Prue Halliwell taught Leo Wyatt how to astral project. She probably learned how to teach it from books she read during the time that she wanted to refine her skills. Although Leo kept this a secret from the sisters for a while, in 2005, he passed on this knowledge to them when they had to vanquish Zankou. A vanquishing which would not only kill Zankou but the sisters as well in the process.

Prue was not the only witch to teach someone else how to astral project. Mrs. Winterbourne, the nursery teacher at Magic School, taught the librarian, Miss Donovan, how to astral project before she went on a sabbatical. Miss Donovan displayed her newly acquired astral projection skills to Paige Matthews while trying to get the post of Literature Professor after the death of Mr. Monkeyshines. Although, it seemed like she had began to learn it a few weeks back before demonstrating it to Paige, the power still exhausted her, which makes sense because she was not born with the power and thus will need more time to get skilled with the ability.

Prue Halliwell
The telekinetic powers of Prue Halliwell advanced during her second year as a witch, gaining the power to astral project, at the time she was at Buckland Auction House. After just finishing a meeting, her sister Piper, who was waiting outside the meeting room, urged Prue to leave. However, Prue's colleague Jack Sheridan urged her to stay and finish a conversation. Feeling the pressure of both her sister and colleague, Prue suddenly slips into unconsciousness and astral projected herself next to Piper. Surprised and confused, Prue returns to her body and awakens.

Prue tried to advance her Astral Projection powers by trying to use Telekinesis while in her astral form, but she was never able to achieve this. However, Prue did become capable of projecting her astral form from one place to another without returning to her physical body; in one case, dematerializing to avoid gun shots then rematerializing at the other side of the room.

In Just Harried, it was revealed that if Prue ignored her inner desires for too long a period, her astral form would taken on a life of its own and manifest while she sleeps or even force her into slumber in order to project itself.

During her brief time with the power of Empathy, Prue was able to wake up for a short amount of time while her astral form was still outside of her body, much like the power of Cloning. She was also able to selectively decorporealize and jump inside the body of the demon, Vinceres. However, all of this was due to the power surge that the power of Empathy had given her. However, Prue did consider it a taste of what her future powers would be like.

Astral Premonition
Astral Premonition is the ability to project one's consciousness into a future event, either as a physical astral form or through the body of one's future self; allowing the user to experience a premonition first-hand. This is a combination of Premonition and Astral Projection and is the closest a Charmed One has gotten to natural Time Travel. The only known user of this power is Phoebe Halliwell. It allows her to see things in more detail and to stay within the future for a longer period of time.
