If you dream of writing in a blog, you should pay close attention to the other symbols in your dream, because they contain an important key to your future happiness.
To dream that someone is reading your blog, or to dream that your blog is hacked or otherwise compromised, indicates that you are keeping secrets. You have difficulties telling others how you really feel.

In dreams, the phoenix is typically a symbol of fresh starts and exciting opportunities. This mythological bird lived alone for hundreds of years and then sang its final song on a nest made of precious spices, an aromatic funeral pyre that was ignited by the sun’s rays.

(If you remember Oedipus’s solution, could it hold the key to your problem?) On the other hand, for most people a dream of the Sphinx will represent Egypt and all the mystery conjured up by that country.
If you dreamed of a serpent-like multi-headed hydra that instantly grew two or more heads whenever one was hacked off, could your unconscious have portrayed your sense of struggling to take one step forward, only to find you have moved two steps back; or did it symbolize the drastic multiplication of problems in waking life? The griffin is said to denote vigilance, combining the attributes of the eagle with those of the lion.
