If we talk about the Biblical meaning of seeing Geckos in dream there are many meanings associated with them. God is trying to warn us to stay away from bad and evil deeds and people. We should keep our thoughts and body clean so that we can firmly walk on the path of enlightenment and finally attain salvation. We should not keep malicious intentions for others, never speak words which might give pain to others and broke their heart and give them tears.
Also God says that this is your another birth or new beginning and you have come in the skin of a human after many births so you should not waste the opportunity to follow God’s path and sacrifice your happiness for others.
If you are earning good you should use them for the sake of less fortunate kids and those animals who are dependent heavily on you. You should provide an umbrella to the one who is walking under rain, shelter to the one who is living on the streets in a snow fall or extreme weather conditions and food to the one who is hungry and is unable to get stomach full of food.
