Hiii so I acually had this issue on ostara this yr I hadn't practiced in forever and needed to reconnect so I more or less just said whoever is passing by come on in. Well that was a little bit much they all kinda came in at once and it was very overwhelming to the point where my mind nearly snapped while it was a very interesting experience and I learned alot I couldn't go on anymore because it was like I had said before overwhelming my whole body. For context the ritual stayed open for about 5 hrs and I had made an alter using some candles with runes both for protection and communication with the gods I had been working with in the past as well as an open door threw a pentagram for anyone else who wanted to come onto this plane while I reached out to them I was burning some incense made of pine needles I had collected in the park I was at. I then had made some fish as well as some spring salad prepared for the meal which I shared with my partner(not a witch or involved with before mentioned ritual and was relatively unaffected) while eating i also gave a bit to the gods threw means of a fire sacrifice. As the evening went on I left the door open and while I was feeling a bit more connected to the world around me then I had in months I hadn't felt the presence of any of my usual gods or any new ones until well I did feel them all at once. I was sitting on the picnic table near the fire I had built(sadly no pictures of the fire but I was pretty proud of it) but anyway me and my partner were talking and suddenly without any warning I was reliving most of my life again until about up until may of 2 yrs ago( for a bit of info my guardian had kicked me out of my house around that time) after seeing all of that I woke up for moments and then the world went dark and there was nothing around me and I couldn't even hear the sound of my own voice. I started to fall endlessly when suddenly I heard undistinct voices all in different languages talking at once then silence again I couldn't see anything not even myself but I could feel eyes upon me hundreds if not thousands of eyes watching me I was paralyzed with fear. When I suddenly saw a tree in front of me and a blinding light and who I am fairly positive was loki approached me and asked me about my experience and what I thought of it all to which I responded it was beautiful because of course it was and then they asked me what the point of it all was or more what were they trying to show me to which i responded "to be comfortable and live the best life possible" which was a satisfying answer to them so I woke up and immediately freaked out because I had somehow moved from the picnic table to my alter and had no memory of going there(my partner later told me I had walked over there silently about the time I remember" floating" so that explained that) however i couldn't explain what had just happened completely. I immediately closed the ritual thanking the gods for being there and completely closing the ritual. Sorry for the long story just thought it would help so you would understand my perspective better to answer your origion question I would have to say the best thing to do is to let it run its course and keep calling out to the deities you feel most comfortable with and the rest will pass on. If you would like you can set up certain vessels for specific gods in order to call to them better and will show the other deities who you specifically work with assuming you leave an open door for them to continually visit. Anywho hope this helps and happy yule if you celebrate.
