You often dream of reptiles, which shows that you have always had a strong desire in your heart, which cannot be realized for special reasons. As for what this desire is, you are not sure, because you have not elaborated on your situation. However, it should have nothing to do with work, but with life, with people you can't avoid in ordinary life but have to face and endure. You have a desire for this person. This person should be a female elder and can't be implemented for a long time. Enduring and suppressing this desire will also make you miserable.
This is the general situation. I hope I can help you.
