Fast summary
The short answer
This is a small curated research library, not an exhaustive literature review or independent clinical assessment. Each note identifies the study, what was examined and a boundary on interpretation. Read the linked paper alongside the relevant guide; a promising result is not a guaranteed personal outcome.
Question
What did the study actually investigate?
Method
Who took part and what was measured?
Limit
Which conclusion would go too far?
How to read these notes
Study design matters. A report from one patient, a short self-report study and a controlled laboratory observation answer different kinds of question. Look for the measured outcome rather than assuming that a convincing title proves a technique works for everybody.
We state when only an abstract or selected accessible passages were checked. An abstract can support a bounded summary, not a reconstruction of every method or result in the full paper. These notes are not evidence of endorsement by the authors.

Aspy’s 2020 International Lucid Dream Induction Study followed 355 selected participants through a baseline week and a practice week. It compared several induction approaches using self-reports, including MILD and SSILD.
The study reported comparable results for MILD and SSILD; the hybrid was not clearly better. Adding reality testing did not improve the measured result over that short period. Selection, self-report and duration limit generalisation and long-term conclusions.

Night waking combined with MILD
Erlacher and Stumbrys examined a combined wake-back-to-bed and MILD procedure in a small sleep-laboratory study. The paper explored specified waking intervals after a period of sleep.
Because the procedure combines elements, its findings do not tell us that waking alone accounts for the outcome. They also do not establish the best timing for every reader. Interrupting sleep has a practical cost even when the research question is interesting.

Experiences at the sleep boundary
Ghibellini and Meier’s review describes the hypnagogic state and highlights varied definitions and methods. It helps organise terminology; it is not a diagnostic instrument or a universal frequency estimate.
Mainieri and colleagues recorded sleep paralysis and two false awakenings in a small laboratory sample. Their comparisons are informative but cannot identify the cause of a reader’s recalled episode.

Bodily perspective is a research question
The Blanke clinical report and Ehrsson laboratory report investigate altered bodily perspective in very different settings. The 2012 review places self-location in a wider sensory-integration framework.
These sources do not verify physical departure from the body or settle every personal interpretation. For these entries we checked accessible abstracts, and the review’s publisher key points—not every full-paper detail.

Research notes are not a care pathway
Finding a paper that describes a similar sensation is not the same as being assessed. A clinical question needs the individual history and appropriate professional judgment.
If an experience is distressing or disrupts sleep, begin with the guide’s support information rather than searching for a theory that matches every detail. Urgent symptoms need urgent services, not more reading.
Sleep paralysis: when to seek helpA library that can be corrected
If you notice that a note misstates a paper’s outcome or access level, send the page address and relevant source to our Contact page. We review substantive corrections against the actual publication.
New studies can change the balance of evidence. We do not silently turn a promising finding into a product claim; guide text and research notes should agree on what remains uncertain.

Are these research notes a systematic review?
No. They are a curated starting library. They do not cover every paper or claim an exhaustive search and appraisal.
Does linking to a paper mean its authors endorse BeyondWake?
No. A reference identifies a source; it does not imply endorsement, partnership or involvement in the project.
Have you read the full text of every listed source?
No. Access levels are recorded in each source note. Some entries are based on accessible abstracts and selected passages only.
Can I use a positive result as a promise that a practice will work?
No. Study population, methods and limitations matter. Research outcomes do not guarantee an individual experience.
