Laura, encountering a white rattlesnake in your parents' backyard signifies a potent symbol of hidden fears or threats within a familiar and usually safe environment. The backyard represents your childhood, family roots, and perhaps unresolved issues from the past. The white color of the rattlesnake indicates purity, but also danger masked in innocence. This duality suggests that you may be confronting a situation in your current life that appears harmless on the surface but has the potential to cause significant distress. The act of being bitten by the snake can be interpreted as a direct confrontation with these hidden anxieties. It implies that the issues you've been avoiding have now manifested in a more urgent and unavoidable manner.
This bite could symbolize a wake-up call to address things you've been neglecting, whether they are related to financial stress, relationship difficulties, or the loss of a loved one. The physical sensation of the bite in the dream may reflect your physical and emotional responses to stress in your waking life. You may often feel the sting of anxiety, which is consistent with your feelings of rarely feeling refreshed after sleep and having difficulty falling asleep. The snake bite could be a metaphor for the way these stresses impact you daily, even if they aren't always at the forefront of your mind.
In terms of your relationship, the dream might be hinting at underlying tensions or unspoken issues that need to be addressed.
