theres white stuff in my oil. can someone tell me if this is normal?

so i drained my oil because i thought there might be gas in it. i now see that it looks like the whole thing is filled with bubbles and theres white stuff when i mix it. yesterday after i rode it for a while the oil was very thin. what are your thoughts?
