But this is not supernatural precognition. It's an illusion created by the Barnum Effect and psychological mechanisms.

Scientific Understanding of Dreams​

What Are Dreams?​

Medical Definition

  • Occurs during REM (Rapid Eye Movement) sleep
  • Random neural brain activity
  • Memory organization, emotion processing
  • No future prediction function

Why Do We Dream?

  1. Memory consolidation (organizing daily experiences)
  2. Emotion processing (stress relief)
  3. Problem-solving simulation
  4. Random brain activity

Scientific Consensus

  • Dreams = Brain's information processing
  • No future prediction ability
  • No symbolic meaning (mostly)

Dream Characteristics​

Ambiguity

  • No clear storyline
  • Jumbled time sequence
  • Illogical progression
  • → Large room for interpretation

Forgetfulness

  • 95% of dreams forgotten within 5 minutes
  • Only part remembered
  • Selective memory (only impressive parts)

Individuality

  • Same symbol, different meanings
  • Varies by personal experience
  • Universal interpretation impossible

Why Do Dream Interpretations Seem True?​

1. Barnum Effect​

Typical Dream Interpretation

"Snake dreams signify wealth, money, fortune.
But sometimes can also mean danger or betrayal.
Trust your intuition."

Problems

  • Two-way interpretation (money or danger)
  • Vagueness ("sometimes")
  • Applies to everyone
  • → Classic Barnum Effect

Experiment

  • Provide same interpretation to 10 people
  • All respond "It's true!"
  • Feels personalized

2. Confirmation Bias​

"Snake Dreams Bring Money"

Scenario 1: Money Arrives

  • "Wow! Dream interpretation was accurate!"
  • Strongly remembered
  • Shared on social media

Scenario 2: No Money

  • "It just hasn't arrived yet" (timing issue)
  • "Small money came in" (found 500 won)
  • "Danger means betrayal" (alternative interpretation)
  • → Not considered wrong

Result

  • Remember only matching instances
  • Ignore/reinterpret misses
  • Illusion of "It matches perfectly!"

3. Retroactive Interpretation​

During Dream: Meaning unknown After Event: "Oh, that dream!"

Example

Monday: Fish dream (ignored, no meaning)
Tuesday: Nothing happens (forgotten)
Wednesday: Friend's pregnancy news (not memorable)
Thursday: Lottery win (not memorable)
Friday: Received pocket money
→ "Ah! Monday's fish dream! It was about wealth!"

Problems

  • Forced matching after the fact
  • Dream → Reality prediction (No)
  • Reality → Dream interpretation (Yes)

4. Probability Illusion​

Probability of "Snake Dream Means Money"

Dream Frequency

  • 70% of Koreans experience snake dreams
  • Dozens of dreams in lifetime

Money Receiving Frequency

  • Salary, pocket money, gifts, found money...
  • More than once a week

Probability Calculation

  • Chance of receiving money within a week after snake dream: Almost 100%
  • "It really matches!" illusion
  • But money received even without snake dream!

5. Ambiguous Symbols​

One Dream, Multiple Interpretations

"Water Dream"

  • Positive: Wealth, prosperity, purification
  • Negative: Danger, drowning, emotional confusion
  • Neutral: Change, flow

Result

  • Can be fitted to any event
  • Good event → Positive interpretation
  • Bad event → Negative interpretation
  • → Impossible to be wrong

Real Case Analysis​

Case 1: Lottery Win Dream​

Claim

  • "Dreamt of a pig and bought a lottery ticket that won!"
  • "Dream told me"

Reality

People who dreamt of pig: 10 million (lifetime)
Lottery ticket purchases: 100 each
→ Total 1 billion attempts
Winning probability: 0.00001%
→ 1,000 winners

1,000 people: "Dream interpretation was accurate!"
9,999,000 people: "..." (silent)

Truth

  • Coincidence
  • Only winners speak (survival bias)
  • Many winners without dreams

Case 2: Pregnancy Precognitive Dream​

Claim

  • "Dreamt of fish and found out about pregnancy"
  • "Isn't that amazing?"

Scientific Explanation

  • Early pregnancy hormone changes → Dream pattern shifts
  • Unconsciously detect pregnancy
  • Body knew, not dream

Additional Factors

  • Trying to get pregnant = Related dreams frequent
  • Confirmation bias active
  • Remember matches, ignore misses

Case 3: Accident Precognitive Dream​

Claim

  • "Had a nightmare and then had an accident"
  • "Dream warned me"

Statistical Reality

Nightmare frequency: 1-2/week (average person)
Minor accident frequency: 2-3/month (falls, bumps...)
→ High overlap probability

Nightmare before accident: "Precognitive dream!"
Good dream before accident: "..." (ignored)
Nightmare without accident: "..." (ignored)

Freud vs Modern Science​

Freud's Dream Theory (1900)​

Claim

  • Dreams = Unconscious expression
  • Symbolic meaning exists
  • Interpretable through psychoanalysis

Examples

  • Snake = Male symbol (sexual desire)
  • House = Self
  • Water = Unconscious

Modern Assessment

  • Failed scientific verification
  • Subjective interpretation (unverifiable)
  • Mostly discarded

Modern Neuroscience​

Activation-Synthesis Theory (1977)

  • Dreams = Random brain activity
  • Brain weaves random signals into story
  • Mostly meaningless

Memory Consolidation Theory (2000s)

  • Dreams = Memory organization process
  • Store important things, delete unnecessary
  • Not future prediction

Scientific Consensus

  • No symbolic meaning in dreams
  • Reflects personal experiences (past)
  • Impossible to predict future
