Blood Drip Effect?

[DaAinGame]

Remember that first level of Amnesia where the petals fell from the ceiling? Well I want to redo that except using blood. Only problem, is I've never worked with particle systems before and my level editor has a tendency to crash whenever I look for particles/materials/decals etc. so I have to get them manually. I've searched on youtube, google, and did a forum search and found no tutorials on how to do it, which also leaves me to ask; is it even possible? This is not a very important item, and can be skipped over, but it would be pretty nice to add something like this to my story. Thanks in advanced!

***EDIT***
I found the particle system I want to use, but how can I set it on a loop? To where a drop of blood falls maybe like, every 5 seconds or so? Right now it drips once as soon as the map starts up and that's it.
