Dream about cobra snake bite is unfortunately a warning for your inability to care for yourself or your helplessness in reaching out to others. You need to exercise care in some fragile situation. You need to be more selfless and reach out to others in their time of need. This points at past mistakes and regrets in your life. You are trying to cover up your true feelings.
Cobra snake bite expresses your limitations and lack of freedom/originality
Comfort will come about through hard work, diligence and prudence. You are feeling trapped by your aspirations. Your dream denotes overwhelming feelings of guilt. Your thinking and beliefs are outdated.
