To dream of a situation being bland represents feelings about a situation being uninteresting or unexceptional. Boring or a lack of excitement. A lack of fun. Feeling that fun or excitement is being intentionally withheld from you. Nothing exceptional going on in your life. Mandatory boredom or enforced patience.
Negatively, something bland in a dream may reflect issues with accepting a boring or uninteresting situation the way it is without end. A possible sign that you need to take action or make a change. Feeling that it’s simply easier to not bother making a change or forcing change.
