Dreaming of snakes can often symbolize transformation, healing, or hidden fears. In your dream, seeing three snakes of different colors could represent various aspects of your life or emotions.

1. Black Snake: This color often relates to the unknown, mystery, or the subconscious. It might indicate feelings of fear or anxiety that you need to confront.
2. White Snake: White typically symbolizes purity, peace, and new beginnings. This could represent a positive change or a desire for clarity and truth in your life.
3. Yellow/Striped Snake: Yellow can symbolize joy, intellect, or caution. The stripes may suggest that you are navigating between different aspects of your life or personality. It could signify a need to be cautious about something that appears joyful but may have underlying complexities.

Overall, the presence of these snakes in your home could suggest that you are dealing with various emotional or psychological changes. It might be beneficial to reflect on your current situation and consider what transformations or truths you need to embrace. Think about how you feel towards these snakes—are you afraid, curious, or indifferent? Your feelings in the dream can provide further insight into your waking life.
