To dream of a heater represents a wish to use something or someone to make your life feel less terrible. Habits you have to make yourself more comfortable during an insensitive or emotionally cold situation. Increasing the warmth, nurturance, or comfort of a situation.
Alternatively, a heater may reflect the sharing of love or being loving towards others. Helping to make a bad time more comfortable for someone else. Make a situation or relationship more hospitable.
