But their dream meaning might not be all that negative.
Insects are known for being very pesky. Nobody wants insects anywhere near them and very very very few people keep them as pets. They cause annoyance, they crawl over you without any regard for what might be comfortable to you and their brains are so small they can’t comprehend when they’re hurting you, or doing something which may get them into great danger. They will bother you forever seemingly. When you have a dream about dead insects or dead bugs it means that you have had a lot of little annoyances like that in your life but they will soon go away and leave you alone. This is good news for you and good news for everyone else too. Finally you will be able to get some peace in your life. Rejoice because you have worked hard for it.
