Halloween 
To dream of Halloween indicates death and the unnatural world. This holiday also represents taking on a different personality or ideal of the self, one in which you don't feel restricted to express your thoughts or ideals.
Pumpkin
To dream of a pumpkin implies open-mindedness to new ideas and experiences. A pumpkin is also closely associated with the female sexuality.
Alternatively, it calls to mind Cinderella, in which a fairy turns a pumpkin into a carriage. The carriage reverted back to a pumpkin at midnight. This represents a situation where time has run out.
Haunted House
Dreaming of a haunted house represents an unsettled past. You may have unresolved problems with past friends or family which are causing you feelings of guilt or anxiety.
Dreaming that you are lost or trapped inside a haunted house means that these feelings have limited your abilities in other aspects of your life.
Jack O Lantern
To dream of a Jack-o-Lantern is an unconscious indication that you are ready and able to overcome any addictions you may be struggling with at this time. The Jack-o-Lantern is a reminder to become a witness to your thoughts surrounding the addiction, whether it is food, drugs, alcohol, sex, shopping, etc. A Jack-O-Lantern with a smile suggests that you would do well to seek help and you will emerge triumphant. A Jack-O-Lantern with a frown implies that you are doing extremely well sorting yourself out and may only need to remain strong to take victorious steps on the road to a new lifestyle.
