Participant: Melanie (Recent college graduate, dual major psychology/philosophy)
Sampling day: 1
Context: Unwrapping heritage chair, found family tree document inside
Experience: Inner hearing a voice (not her own but familiar 'thought voice') saying in accelerated speech: 'How funny it is that I just received this chair and now I have to plan who is to inherit.' Simultaneously, a rosy-yellow glow throughout her head associated with the humor of the thought — a 360-degree luminance she regularly experiences with humor.
Categories: inner_speaking, feeling
Multiple simultaneous experiences: yes
Notes: Russ classified as inner hearing rather than inner speaking. Voice was smoother, more modulated, lower pitch than her speaking voice. Speech felt compressed/faster than normal but not rushed.

Participant: Melanie (Recent college graduate, dual major psychology/philosophy)
Sampling day: 1
Context: Walking between kitchen and dining room waiting for boyfriend to finish shower so she could start dinner
Experience: Inner speaking (more spoken than heard, ~80% on spokenness scale): 'You can think you're really busy but during those busy times there are still periods of empty time.' Hybrid between her own voice and the 'thought voice' from 1.1. Also visually aware of microwave and stove in front of her.
Categories: inner_speaking, sensory_awareness
Multiple simultaneous experiences: yes
Notes: Unlike beep 1.1, this was more speaking than hearing. Same accelerated quality. She was more aware of surroundings than in 1.1.

Participant: Melanie (Recent college graduate, dual major psychology/philosophy)
Sampling day: 1
Context: Having dinner with boyfriend, discussing country house and shed addition
Experience: Just finished saying aloud 'Oh, I remember the shed now.' Three things in awareness: (1) speaking aloud, with awareness of mouth closing at end of utterance, (2) feeling the musculature of the speaking act ending, and (3) a crystal-clear, detailed inner image of the inside of the shed — viewed from just inside the front door, dark interior with small window, coat hooks with a windbreaker jacket, unfinished bathroom cutout, bench, all in light oak wood. Image was still, like a snapshot, and seen as through her own eyes in normal visual field.
Categories: inner_seeing, sensory_awareness
Multiple simultaneous experiences: yes
Notes: Image was a memory snapshot from the one time she visited. Equally clear across entire visual field, not focused on any one element. She could describe specific details like sleeve lengths of the jacket.

Sampling day: 1
Context: Watching movie with boyfriend, screen frozen on MGM lion logo with cycling background colors
Experience: Two things in awareness: (1) hearing boyfriend Alex say 'Didn't the lion used to...' and understanding his question, and (2) paying particular visual attention to the green color of the screen background, which reminded her of the MGM Grand hotel. The greenness was absorbing — she was 'into' it in a way different from casually seeing the microwave in beep 1.2.
Categories: sensory_awareness
Multiple simultaneous experiences: yes
Notes: No inner speech or imagery. A perceptual experience — watching external world with particular attention to color quality.
