It is not uncommon for pregnant women to experience vivid dreams, including ones about their spouse cheating. These dreams can be distressing and impact your self-esteem. While the exact cause is unknown, hormonal changes, anxiety, and subconscious fears may contribute to these dreams. To cope with them, try relaxation techniques before bed, such as deep breathing or meditation. Talk to your partner about your concerns and seek reassurance from them. Consider keeping a dream journal to identify patterns or triggers. If the dreams persist and significantly affect your well-being, consult a healthcare professional for further guidance and support. Remember that these dreams do not reflect reality and do not define your worth as a person or partner.
