First time reusing yeast

[hfd73]

I brewed a Pale ale about a week ago, then yesterday transferred it to a secondary while I was brewing an amber ale. I poured the Amber ale wort on the old yeast cake and within 3 hours it was bubbling away. It took off like crazy kept going for 22 hours!! I think the CO2 depleted the O2 in my pantry, cuz I would get a little dizzy everytime I walked in there to check on it. It's been over 30hours and it has pretty much stopped bubbling. Is that normal for using so much yeast on a 5gal batch? I've been doing partial grain for almost 2years and usually have a lag time of about 18 hours with active fermentation for at least 2 days using liquid yeast without a starter. I'm ready to get into all grain brewing in the next couple weeks.
Thanks

How did you aerate your wort?

Poured through a sanitized colander and then a stirred pretty good with a sanitized whisk. It had about 2inches of foam by the time I was done.

Yes, that kind of activity is very normal if you use your yeast cake. Blow off is common too. I pitch on the cake once in a while just for the fun of watching the wild fermentation.
