myjellybean Interpretation:
If you dreamed of spelling words correctly, it signifies success in your current situation. But if you misspelled any words, your dream is a warning to be on guard against hidden hostility.
Emphasizing words of importance; research for clarity
Success to all your plans.
This is likely to be a rather obscure dream, but a dream of not being able to spell suggests the inability to work something out, get something right. On the other hand, since illiteracy is generally regarded as shameful, there may be an allusion to some aspect of your waking life which you would rather no one knew about. The word which you could not spell may represent a clue to the dream’s intention. Do you need to spell something out in detail?
