I don't know
I dream of lizards very often, sometimes two similar lizards, some times many lizards....
They don't harm me but I wake up in horror

Because I have little else to go on for your dream with the lack of extra details of your dreams, I can only give you some dream dictinary explanations,

"...signifies your primal instincts and reactions toward sex, food, etc. and your anxieties toward these feelings. The lizard can also be representative of a person who you view as cold-blooded, fearful, or thick-skinned. On a more positive note, the lizard also symbolizes emerging creativity, renewal, and revitalization. It may also suggest that you are well-grounded [because they are so close to the ground]."

Thank you so much for your informative reply,

I can tell you more on my dreams...
Every time I see two lizards on the wall facing each other e.g. fishes in the zodiac sign of Pisces...
Sometimes I see the third one entering into the scene..
My dream is full of light and very bright every time
Please help

What is the scenery? What else happens in the dream? Do you interact with the lizards? Are there any other people? What's the story in the dreams?

Well, I've to say something in this regard, though I'm not a professional dream interpreter. with due respect to the theoretical significances of dream symbols that exist and that professional dream interpreters refer to, I cannot but having doubt in them. and the significances are also such multitudinous that it at times seems very confusing. a particular thing in a dream 'may indicate' this and that.

With the common sense, that guess I have, I think the meanings of things or symbols in dreams definitely have something to do with what first comes to the mind of the dreamer when he/she thinks of that object.

Elgina, you just try to think what comes to your mind when you think of the lizards. who can say, this dream may be a reflection of your worry about people who keep changing their stances?
