==Hypnagogic phenomena==

===Visual===

Initially, hypnagogia will manifest itself as moving blobs of color (see ''[[phosphene]]''), in the form of lines, speckles, and geometrical shapes. Those patterns become increasingly complex, and can be easily controlled on demand by focusing on specific shapes. Eventually, they can form simple images, even three-dimensional.

===Auditory===

These can be faint to loud sounds, ~~almost exclusively~~ short, nonsensical fragments of speech, everyday noises, or a voice calling one's name. Exceptionally, longer-lasting auditory hallucinations can also be heard, ~~like~~ music. Some people report hearing very loud noises, like crashes, gunshots or explosions, which is a sleep disorder known as the ''exploding head syndrome''.

===Other senses===

Olfactory, gustatory or tactile sensations are also possible in this state, and they are fleeting in nature. Sometimes, there is also some degree of [[synesthesia]], in which a real stimulus (such as a sound) may trigger perception of flashes or images. ~~Proprioceptive hallucinations, like floating~~ limbs, feeling that one's body is in a different position from what it actually is, or changes in perceived body size are common too.
