Continuous forms of see
When see means ‘meet’, ‘interview’, ‘talk to’ or ‘go out with’, progressive forms are possible.

- I am seeing the doctor tomorrow.
See can also be used in the progressive when we mean that somebody is imagining things that are not there.
- ‘Look! There is a camel!’ ‘You are seeing things.’
The expression I will see means I will consider the matter. Let me see means give me time to think or recall. Note that a preposition is necessary before the object in these cases.
