Your dream seems to be a reflection of the stress and exhaustion you are experiencing in your waking life, particularly related to caring for your children. Here are some interpretations of the key elements:

1. Physical Discomfort: The discomfort you felt in your dream mirrors your physical sensations of being overwhelmed and tired. It suggests a need for rest and self-care, as your body is signaling that it needs attention.
2. The Tree of Life: This symbolizes growth, nourishment, and a connection to vitality. The glowing colors could represent hope and potential, while the withering indicates your fear of draining this source of energy or support. It might reflect your desire to find something that can rejuvenate you, but also the anxiety that seeking help might disrupt that beauty or balance.
3. Touching the Tree: Your hesitation to fully engage with the tree might symbolize your struggle to find a balance between seeking help and feeling like you might be a burden. The tree regaining its beauty when you withdrew your hand suggests that sometimes stepping back might be necessary for preservation, either of your own energy or of the things you value.
4. In and Out of Sleep: This represents the cyclical nature of your current stress and fatigue, where you’re unable to find true peace or rest. It highlights the frustration of feeling trapped in a situation where you can’t escape your responsibilities or find relief.
5. Crying Twins: The twins crying may symbolize the duality of your responsibilities and the emotional burden you're carrying. It suggests that there may be multiple aspects of your life that need attention, and the frustration you feel indicates a longing for resolution or understanding.

Overall, this dream emphasizes the need for self-care and finding a balance between caring for others and caring for yourself. It may be beneficial to seek support from friends, family, or professionals to help alleviate some of the pressure you’re feeling. Making time for yourself, even in small ways, could help restore your energy and improve your overall well-being.
