Yes.

We have had several enquiries recently about mixing tenses. Some learners appear to be under the impression that only one tense can be used for all the verbs in one sentence. This is just not so. There is no restriction on what tenses we can use and mix, if they are appropriate for the context:

I went to a party last night. While I was there I thought it was great, today I realised that it was actually pretty awful and tomorrow I will probably decide that it was the worst party I have ever been to.

Interesting!

I saw a dead cat yesterday, and it's still on the roof.
