Attic
To dream of an attic represents things you think that you don't respect or intentionally neglect. Anything or anyone in the attic symbolizes what it is that you don't respect. An "out of sight otu of mind" attitude about something in your life.
Negatively, an attic may be a sign that you are intentionally neglecting something or someone until it serves you. Taking a risk disregarding something important
To dream of yourself being in an attic may reflect waking life situations were you are intentionally and needlessly isolating yourself from people. Feeling intentionally neglected or that people don't think you are important. Accepting yourself as someone who never needs to matter.
Example: A man dreamed of a man being inside his attic. In waking life he had a demanding boss whom he regularly lied to and spoke ill of behind his back.
Example 2: A man dreamed of being in an attic looking at birdhouses. In waking life he was living with his parents to save money while looking for a way to attract people to his skills to get opportunities. In this case the attic may have reflected his feelings about intentionally neglecting to help pay any of this parents bills while he lived with them.
