What is this? Is this a problem?

Today my dad woke up with my sister making a weird breathing. Noise.. like her bubbling up her spit in her mouth and this is not the only time something. Happened like that... in December she had a seizure... today we dont know what happened she's in the hospital right now
Anywho what happened. Was is that. She made a weird noise and my dad woke up shaking her not in a bad way but to wake her up... normally she would respond but like when she had a seizure... she didn't
Then my dad went outside with her and he tryes to get her to respond but all she did was opened her eyes and ignored... whenever my dad let go of her she went walking. With her eyes closed... tho she would. Do the same if he held on to her she would try and leave... what is this? I mean what happened

Also is it allowed for a ambulance guy to come saying. She is perfectly. Fine when we are concerned. Cause last time she had a seizure so my dad stayed argueing with the guy
Please answer asap
