Dreaming that you are pregnant means that you have some burdens in your mind now, and you want to get rid of something, but you feel embarrassed. Four or five months implies a certain delay in time, because of some superficial problems (bulging belly) but some reluctance.
The second dream:
I don't know if you are disturbed by what happened between you and your boyfriend recently. Just like people often compare marriage to a pair of shoes, only the wearer knows whether it fits. This dream you have seems to come from it. I can only infer that you may be faced with other opportunities to choose a spouse, or have the idea of finding another boyfriend, but there are some factors that make you hesitate. You should be a conservative girl, and have the idea of being faithful emotionally. Although you are indifferent to your previous feelings, you are still trying to recover. You have been trying to find various reasons for yourself to get back together with your ex-boyfriend.
The third dream:
The first two are basically based on your recent thoughts. Three dreams continue the last dream, and you are nostalgic, but there are many factors that make it difficult for you to convince yourself and worry a little. You didn't break up with your current boyfriend. On the one hand, you are afraid that the person you are looking for is not as good as your boyfriend. On the other hand, if you don't break up, your current boyfriend has many shortcomings or some factors that you reject, which makes you unwilling to be with him. The direct analysis of throwing a basin and washing feet may imply that you don't want to be with your current boyfriend, and you are disappointed in some ways.
I don't know whether you dreamed for several nights separately or for a whole night in a row. I don't know what you were feeling in your dream when you dreamed, and I don't know what you have been thinking recently or what happened around you, but you didn't express it. These are very important factors in analyzing dreams.
How can I put it? Believe in your feelings and analyze yourself realistically, whether you can continue and whether you are happy together. It's good for everyone to make a decision as soon as possible.
