Levitation refers to raising an object against the force of gravity in such a way that it remains suspended without any physical contact.
It is quite possible to do this without leaving the realm of physics, the most usual being magnetic levitation where the force of magnetism is used for this purpose.
In terms of pseudoscience it refers to the ability to manage this raising by the power of the human mind. This has never been demonstrated — much less repeated — under controlled conditions and is consequently a pseudoscience.
