A mental construct, thought-form, or thoughtform, is anything constructed within the mind, using tulpamancy. Mental constructs range from simple mental visualisations, to vast wonderlands, servitors and tulpas.
- Main article: Tulpa
A tulpa is a perceived autonomous conscious sentience, and is commonly viewed as the most advanced and complex form of mental construct. Some argue that tulpas do not belong on the same scale as other thought-forms, due to their nature as being perceived sentient, conscious and independent from their creator.
- Main article: Servitor
A servitor is a mental construct that serves a purpose.
Thought-form is an umbrella term synonymous with mental construct, and can encompass any imagined stimuli. The act of creating a mental construct is commonly referred to as forcing.
- Main article: Wonderland
A wonderland is a self-persistent imagined location.
