The suggestion that self-organising plasma structures in the atmosphere might behave in ways that read as purposeful. Speculative, and never demonstrated to produce anything life-like, but it belongs here because it is one of the few entries offered as a hypothesis rather than a testimony. Compare atmospheric sprites, which are real and are not alive.
Reported with some consistency but carrying no origin claim in the encounters themselves. Filing these as alien is an assumption the listener adds.
Degree of embodiment: 2, energetic or subtle
Scale, 1 to 5
5 is an ordinary biological body. 4 is physical but manifests oddly. 3 comes and goes. 2 is energetic or subtle. 1 is consciousness with no persistent form. Note that this tends to fall as a tradition ages.
S: speculative hypothesis
Source code
Offered explicitly as a proposal rather than a report. Rare in this field, and worth noticing when it happens.
Atmospheric sprites
Real phenomenon
Transient luminous events: enormous, extremely brief electrical discharges roughly 50 to 90 km above thunderstorms, photographed since 1989. Physicists named them after the folkloric creature because both are luminous and gone in an instant. They are not alive, and the coincidence is only a coincidence.
No practice attached
Tradition-side
There is nothing to do here: no inherited method of engagement, whether the tradition is a text, an argument or a set of reports. Anyone offering you one has invented it.
Deliberate contact work
Read this first
The hazard in this subject attaches to the method, not to which name you aim it at. Ouija work, invocation, sustained channelling, induced hypnagogia, deliberate sleep deprivation and hypnotic regression are the practices associated with difficulty, and a session aimed at a benevolent civilisation is not safer than one aimed at something considered lower. What raises risk is doing it alone, doing it repeatedly, doing it while sleep-deprived, and doing it with an existing vulnerability to psychosis, mania or dissociation. People who get into trouble here overwhelmingly got there through practice, not through reading.
Who should be careful
Practice-side
Anyone with a personal or family history of psychosis, bipolar disorder or dissociative conditions, anyone in acute crisis, and anyone isolated from people who would notice a change in them. Intensive contact practice is destabilising by design (that is what it is for), and destabilisation lands hardest on people already close to an edge.
