Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose vivid/crazy/weird dreams, we could:

  • Research the topic
  • Find a doctor with the time
  • Use a diagnostic computer system.
The process is the same, whichever method is used.

Step 1: List all Possible Causes

We begin by identifying the disease conditions which have "vivid/crazy/weird dreams" as a symptom.  Here are eight possibilities:
  • Pregnancy Issues
  • Diabetes II
  • Anxiety
  • Hypoglycemia
  • Depression
  • Stress
  • Bipolar Disorder
  • Drug Side-Effects

Step 2: Build a Symptom Checklist

We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
recently going through divorce
being serious about life
severe nail biting
absent sexual desire
high refined white flour consumption
breast soreness during cycle
regular postprandial somnolence
facial burning/tingling
significant bowel movement changes
often waking up with dry eyes
occasional rapid, shallow breathing
high air pollution exposure
... and more than 140 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of vivid/crazy/weird dreams:
Cause Probability Status
Diabetes II 93% Confirm
Depression 25% Unlikely
Pregnancy Issues 12% Unlikely
Bipolar Disorder 1% Ruled out
Anxiety 1% Ruled out
Stress 0% Ruled out
Hypoglycemia 0% Ruled out
Drug Side-Effects 0% Ruled out
* This is a simple example to illustrate the process

Arriving at a Correct Diagnosis

The Analyst™ is our online diagnosis tool that learns all about you through a straightforward process of multi-level questioning, providing diagnosis at the end.

In the Sleep-Related Symptoms section of the questionnaire, The Analyst™ will ask the following question about frequency of bizarre/vivid dreams:
Roughly how often do you experience very strange dreams? Do not include scary dreams (nightmares).
Possible responses:
→ Don't know / I (usually) don't remember my dreams
→ Never / rarely / less than once a year
→ Occasionally, less than once a month
→ Regularly, more than once a month
→ Frequently, more than once a week
Based on your response to this question, which may indicate absence of bizarre dreams, occasional bizarre dreams, regular bizarre dreams or frequent bizarre dreams, The Analyst™ will consider possibilities such as:
(Prescription) Drug Side-Effects

Certain medications can increase vivid dreaming, for example depression medication, sleep medication, and some over-the-counter drugs.


Those who suffer from anxiety will often have prolonged, vivid, detailed dreams rather than the usual short bursts of dream activity.  There is increased activity in the brain of an anxious person.

Bipolar Disorder, Manic-Depressive

Those with bipolar disorder can experience very vivid dreams.


Studies have shown that people with depression can have three or four times the normal number of dreams.

Diabetes Type II

Diabetes disrupts REM sleep and affects the brain's ability to separate dreams from waking perceptions.


When the brain senses low glucose levels, it will employ various mechanisms to try and rectify the situation.  One way is by releasing adrenaline, which can cause vivid dreams that are accompanied by a feeling of being "wired" (nervous, tense, on edge, highly stimulated).

Pregnancy-Related Issues

Many pregnant women experience vivid dreams, both pleasant and disturbing.  These appear to be caused by hormonal changes and are a way for an expectant mother to come to terms with the fears that accompany the birth of a child.


It is believed that when a person is stressed, the brain has difficulty processing all the information that it picks up during the day.  It continues to process during the night, which in turn can lead to weird dreams.

... and also rule out issues such as:
Vitamin B6 Requirement

Vivid dreams can be a warning sign of excess vitamin B6 (pyridoxine) in the body, which can lead to neurological disorders if it continues.
