The person who sees himself bitten by a dog in a dream is in some troubles or is struggling to get rid of those who are hostile to him. This dream shows the worries and sometimes the phobias that the dreamer has.
Bad dreams can be seen due to being in a period where enemies or rivals are dealt with and both materially and morally damaged. Situations such as having a very difficult time and being in the middle of an unwanted argument also cause such dreams to be seen.
