Socio-Psychological hypothesis (Ufology)
The Socio-Psychological hypothesis (SPH), or psychosocial hypothesis (PSH), is a hypothesis in ufology that proposes some UFO contacts are best explained as being culturally shaped visionary experiences, as opposed to being direct encounters with otherworldly or interdimensional forms and craft.
