The Phenomenology of Hallucinations
#hallucinations #phenomenology #perception #psychiatry #subjective experience #sensory modalities #clinical diagnosis
📌 Key Takeaways
- Hallucinations are perceptual experiences without external stimuli, often detailed and vivid.
- They can occur across sensory modalities, including auditory, visual, and tactile forms.
- Phenomenology examines the subjective qualities and lived experience of hallucinations.
- Understanding these experiences is crucial for clinical diagnosis and treatment in psychiatry.

Abstract: We show that language models hallucinate not because they fail to detect uncertainty, but because of a failure to integrate it into output generation. Across architectures, uncertain inputs are reliably identified, occupying high-dimensional regions with 2-3$\times$ the intrinsic dimensionality of factual inputs. However, this internal signal is weakly coupled to the output layer: uncertainty migrates into low-sensitivity subspaces, becoming geome
