When I came you were sleeping. I trying to construct sentences by working out the use of the verbs. Please feel free to corect me

Thank you

(Ben) Geldiðimde (sen) uyuyordun.

or

(ben) Geldiðim zaman (sen) uyuyordun

they have the same meaning.

(you can use ben and sen if you want, you may use only one or omit both )
