Vivid dreams during pregnancy.

 
Vivid dreams during pregnancy are normal and healthy, and are often caused by hormonal changes, increased blood flow, and heightened emotions. Other factors that can contribute to vivid dreams during pregnancy include:
 
Sleep disturbances
Waking up more frequently at night to urinate or due to discomfort can disrupt REM sleep, which is when dreams occur. Waking up in the middle of a dream cycle can make it easier to remember the dream in great detail.
 
Stress
Pregnancy can be a stressful time, and increased stress or anxiety can lead to more intense dreams or nightmares.
 
Increased need for sleep
Pregnant women need to sleep more, and the more you sleep, the more you dream.
 
Some common themes in pregnancy dreams include:
 
Water
Dreams about water, swimming, or water creatures may be a sign of the amniotic fluid building up in the body.
 
Buildings
Pregnant women often dream about buildings, such as factories or shipyards, which may reflect the "making" of a baby.
 
Driving
Pregnant women may dream of driving trucks, buses, or other vehicles that are harder to manoeuvre than cars, which may reflect their perception of awkward movement.
 
To improve sleep quality and reduce vivid dreams, you can try:
Following a regular and calm night-time routine
Avoiding liquids a few hours before bedtime
Avoiding using your phone or other blue-light emitting screens when in bed
Trying to sleep on your left side
Being physically active during the day
 
If you have persistent and distressing dreams, you can speak with a doctor or therapist
