Variations in Dream Recall Frequency and Dream Theme Diversity by Age and Sex

Open access

Abstract

We assessed dream recall frequency (DRF) and dream theme diversity (DTD) with an internet questionnaire among a cohort of 28,888 male and female participants aged 10-79 years in a cross-sectional design. DRF increased from adolescence (ages 10-19) to early adulthood (20-29) and then decreased again for the next 20 years. The nature of this decrease differed for males and females. For males, it began earlier (30-39), proceeded more gradually, and reached a nadir earlier (40-49) than it did for females. For females, it began later (40-49), dropped more abruptly, and reached nadir later (50-59). Marked sex differences were observed for age strata 10-19 through 40-49 and year-by-year analyses estimated the window for these differences to be more precisely from 14 to 44 years. DTD decreased linearly with age for both sexes up to 50-59 and then dropped even more sharply for 60-79. There was a sex difference favoring males on this measure but only for ages 10-19. Findings replicate, in a single sample, those from several previous studies showing an increase in DRF from adolescence to early adulthood, a subsequent decrease primarily in early and middle adulthood, and different patterns of age-related decrease in the two sexes. Age-related changes in sleep structure, such as decreasing %REM sleep which parallel the observed dream recall changes, might help explain these findings, but these sleep changes are much smaller and more gradual in nature. Changes in the phase and amplitude of circadian rhythms of REM propensity and generational differences in life experiences may also account for some part of the findings. That decreases in DTD parallel known age-related decreases in episodic and autobiographical memory may signify that this new diversity measure indexes an aspect of autobiographical memory that also influences dream recall.

  • There is no agreement about dream content qualitative features and dream recall rates in the life span among age groups.

    “Nonetheless dream content and dream recall studies have been made both on healthy cohort and pathological samples at any age, there is no agreement about dream content qualitative features and dream recall rates in the life span among age groups.5,67–69,72”

    From Spotlight on dream recall: the ages of dreams (2018) · cites this paper as [72]

    The Introduction (page unavailable) says there is a “relatively broad consensus” from survey and laboratory studies that dream recall decreases with age—the opposite of the claim that there is no agreement about recall rates across age groups. The Discussion reports that this study’s recall findings replicate previous studies. The paper discusses uncertainty about explanations for age-related dream-theme diversity, but that does not support the claim of no agreement about dream recall. (LLM, conf=0.89)

    Checked by a reasoning model — may be wrong.

  • Changes in dream recall rate seem to follow a linear decrement from first adulthood to late ages.

    “the changes in dream recall rate seem to follow a linear decrement from first adulthood to late ages.72”

    From Spotlight on dream recall: the ages of dreams (2018) · cites this paper as [72]

    The Discussion (‘Decrease in dream recall frequency’) says the decline occurs primarily in early-to-middle adulthood rather than later years, and describes different patterns for males and females. The Introduction likewise says several studies found an abrupt early decline rather than a progressive decrease across the lifespan. This contradicts a linear decrement from early adulthood to late age. (LLM, conf=0.88)

    Checked by a reasoning model — may be wrong.

  • The modification of memory performance across early childhood parallels the improvement of dream recall rates in children.

    “The modification of memory performance across early childhood, due in the firsts ages to the so-called infantile amnesia72–74 and subsequently to the development of cognitive functions,67 parallel the improvement of dream recall rates in children.”

    From Spotlight on dream recall: the ages of dreams (2018) · cites this paper as [72]

    The Introduction (page unavailable) proposes that age-related changes in dreaming might parallel changes in memory, and the Discussion reports increasing dream recall from age 10 through adolescence. The paper does not establish that memory performance and dream recall improve in parallel during early childhood; its youngest participants were 10 years old, and the proposed memory connection is tentative. (LLM, conf=0.85)

  • Gender differences, gender orientation, and personality also affect dream recall frequency and dream features.

    “some studies revealed that gender differences, gender orientation,72,143–145 and personality146 also affect dream recall frequency and dream features.”

    From Spotlight on dream recall: the ages of dreams (2018) · cites this paper as [72]

    The Results (Dream recall frequency; page not provided) find that females recalled more dreams than males in several age groups, supporting the sex-difference portion. The Results (Dream theme diversity; page not provided) find no overall sex effect on theme diversity, and the cited paper does not address gender orientation. Personality has a separate citation in the citing sentence and is not attributed to this paper. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Dream recall frequency seems already reduced in first and middle adulthood.

    “dream recall frequency seems already reduced in first and middle adulthood.72,132”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
