Trapped by lockdown now possible Tax resident nightmare.

We came for three months in January.   We are not resident in Spain but have a house.  We have had four ferries cancelled on us since our original return date of March 26 th one after the other. We didn’t want to drive all the way up to Bilbao to have another cancel at the last minute and we wouldn’t be able to get back down till next ferry. We would have been living in a park homeless up there . 72 and 62 year olds No motorway services no hotels, it’s easy now to forget what a big deal it was ,and frightening , the not knowing what was next to close down, maybe the Chunnel. So we decided to stay put till things were improved. Our ferry for this Saturday 25th was cancelled on Friday !     We are now booked on 21st July ! Now I hear that if you have stayed more than 183 days in the year! We will now have to pay Spanish Tax on our worldwide income and assets ! Anyone got any input on this ?
